ISO Viscosity Grades

Certainly! ISO Viscosity Grades play a crucial role in the world of lubrication. Let’s dive into it.

What are ISO Viscosity Grades?

• ISO Viscosity Grades, also known as ISO VG, provide a standardized method for classifying industrial liquid lubricants based on their viscosity. These grades help lubricant suppliers, equipment designers, and users communicate effectively about lubricant requirements.
• The ISO VG system ensures consistency by defining viscosity ranges for each grade. The midpoint of each range represents the nominal viscosity value, and the actual viscosity of a lubricant can vary by ±10% from this midpoint.

Understanding Viscosity:

• Viscosity measures an oil’s resistance to flow (shear stress) under specific conditions. It reflects how well the oil stays put when subjected to mechanical forces.
• Imagine a water-skier cutting through water. Water has a viscosity of 1 centistoke (cSt), which is at the lower end of the viscosity scale. If the skier were skiing on a lake of SAE 90/ISO 220 gear oil, the spray generated would be considerably less because the oil resists the ski’s force more effectively.

Absolute Viscosity:

• Absolute viscosity (also called dynamic viscosity) is a measure of how a fluid behaves under pressure. It is expressed in centipoises (cP). Machine designers are interested in this property, especially for pressurized hydraulic lines.

ISO Viscosity Grade Numbers:

• Each ISO viscosity grade corresponds to a specific viscosity bracket. For example:
  • ISO VG 32 relates to a viscosity bracket of 28.8 to 35.2 mm²/s, with a midpoint of 32.0 mm²/s.
  • The ISO VG system covers a wide range of viscosities, allowing users to select the right lubricant for their equipment.

In summary, ISO Viscosity Grades provide a common language for lubrication professionals, ensuring clear communication and effective lubricant selection.

This classification defines 20 viscosity grades in the range of 2 to 3200 square millimeters per second (1 mm2/s = equals 1 cSt) at 40ºC (104ºF). For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils.

Each viscosity grade is designated by the nearest whole number to its midpoint kinematic viscosity in mm2/s at 40ºC (104ºF), and a range of +/- 10 percent of this value is permitted. The 20 viscosity grades with the limits appropriate to each are listed in Table 1.

The classification is based on the principle that the midpoint (nominal) kinematic viscosity of each grade should be approximately 50 percent greater than that of the preceding one. The division of each decade into six equal logarithmic steps provides such a system and permits a uniform progression from decade to decade. The logarithmic series has been rounded off for the sake of simplicity. Even so, the maximum deviation for the midpoint viscosities from the logarithmic series is 2.2 percent.

Table 2 pulls together some popular viscosity measurement methods into one table. If the practitioner is comfortable with one particular measure but would like to see the correlating viscosity range in another measure, all he must to do is place a straight horizontal line through his chosen viscosity type and see its correlation within the other types of measures.

While it is true that some viscosity grades will be left out of the mix as companies move toward adopting the ISO designation, it is not necessary that the users of those products have to move away from them. Further, there is no intention to offer quality definition of lubricants with this scale. That a product has an ISO VG number associated with it has no bearing on its performance characteristics.

The ISO designation has been under development since 1975. The most recent release in 1992 (ISO 3448) contains 20 gradients. This covers nearly every type of application that the lubricant practitioner can expect to encounter. The lubricant manufacturing community has accepted the recommended ISO gradients and has devoted appreciable effort and energy to conform to the new grading approach with old and new products.

It is unlikely that all of us who learned about the use of oil from our mentors or friends under the hood of a car will ever abandon the SAE grading system. We don’t have to. At least for automotive oils, we can expect to continue to see the 10- 20- 30- 40- 50- values used. It is likely, however, that in the industrial lubrication world there will be more ISO dependence in the future.

RTD theory

RTD stands for Resistance Temperature Detector. It is a type of temperature sensor that measures temperature by changes in the electrical resistance of a metal wire or film as temperature changes. RTDs are commonly used in applications where high accuracy and stability are required, such as industrial process control, HVAC systems, and laboratory equipment.

The theory behind RTDs is based on the fundamental principle that the electrical resistance of a conductor changes with temperature. In RTDs, this change in resistance is typically linear and predictable over a certain temperature range.

Here's a brief overview of the theory behind RTDs:

1. Temperature-Resistance Relationship: RTDs are typically made of materials with a predictable and linear relationship between resistance and temperature. The most common material used for RTDs is platinum (Pt), although other metals such as nickel (Ni) and copper (Cu) can also be used. Platinum RTDs offer excellent stability, linearity, and accuracy over a wide temperature range.

2. Positive Temperature Coefficient (PTC): Most RTDs exhibit a positive temperature coefficient, meaning that as temperature increases, the resistance of the RTD also increases. This relationship is described by the Callendar-Van Dusen equation, which is used to calculate the temperature from the measured resistance.

3. Resistance-Temperature Curve: The resistance of an RTD is typically measured using a Wheatstone bridge circuit, where the RTD is one of the arms of the bridge. By applying a known excitation voltage and measuring the voltage across the RTD, the resistance can be calculated using Ohm's law. The resistance value is then converted to temperature using calibration curves or polynomial equations specific to the RTD type and material.

4. Temperature Coefficient of Resistance (TCR): The temperature coefficient of resistance (TCR) is a measure of how much the resistance of a material changes with temperature. For RTDs, the TCR is specified by the manufacturer and determines the sensitivity and accuracy of the sensor. Platinum RTDs typically have a TCR of around 0.00385 Ω/Ω/°C, meaning that the resistance changes by 0.385% per degree Celsius change in temperature.

5. Linear Range: RTDs have a linear temperature-resistance relationship over a specific temperature range, typically from -200°C to +850°C for platinum RTDs. Beyond this range, the relationship may deviate from linearity, and special calibration may be required.

In summary, RTDs operate on the principle of measuring the change in resistance of a metal wire or film as temperature changes. This change in resistance is predictable and linear over a certain temperature range, allowing RTDs to provide accurate and stable temperature measurements in various applications.

Vinegar and its common ways for cleaning

Vinegar is a liquid typically made through the fermentation of ethanol alcohol. It's composed of acetic acid and water, along with small amounts of other compounds that give it its distinct flavor and aroma. Vinegar has been used for thousands of years for various culinary, medicinal, and household purposes.

The process of making vinegar involves the fermentation of sugars or alcohol by acetic acid bacteria. The bacteria convert the alcohol into acetic acid, which gives vinegar its sour taste and pungent odor. Depending on the starting ingredients and fermentation process, various types of vinegar are produced, such as white distilled vinegar, apple cider vinegar, red wine vinegar, white wine vinegar, balsamic vinegar, and rice vinegar.

Vinegar is a versatile ingredient in cooking, used for flavoring, pickling, and preserving foods. It's also utilized in salad dressings, marinades, sauces, and condiments. Beyond culinary applications, vinegar is employed for its cleaning, disinfecting, and deodorizing properties in household chores. Due to its acidity, vinegar can help dissolve mineral deposits, remove stains, and inhibit the growth of bacteria and mold.

Overall, vinegar is a widely available and affordable product that serves numerous purposes in both the kitchen and household maintenance.

Cleaning with vinegar is a great eco-friendly and budget-friendly option for various household tasks. Vinegar, especially white distilled vinegar, is acidic, which gives it its cleaning properties. Here are some common ways you can use vinegar for cleaning:

1. Surface cleaning: Mix equal parts of water and vinegar in a spray bottle to create a general-purpose cleaner. This solution can be used to clean kitchen countertops, appliances, bathroom surfaces, and more.

2. Glass cleaning: Vinegar is excellent for cleaning glass surfaces such as windows and mirrors. Mix vinegar with water in a spray bottle, spray it onto the glass surface, and wipe it off with a clean cloth or newspaper for a streak-free shine.

3. Removing odors: Vinegar is effective at neutralizing and removing odors. You can use it to deodorize surfaces like cutting boards, trash cans, and refrigerators by wiping them down with a vinegar solution.

4. Unclogging drains: Pouring a mixture of baking soda and vinegar down a clogged drain can help dissolve buildup and clear minor blockages. Follow it up with hot water to flush out the debris.

5. Removing stains: Vinegar can be used to remove stains from fabrics, carpets, and upholstery. Mix vinegar with water and dab the solution onto the stained area, then blot with a clean cloth until the stain lifts.

6. Cleaning appliances: Vinegar can be used to descale and clean appliances like coffee makers, kettles, and dishwashers. Run a cycle with vinegar instead of water to remove mineral buildup and bacteria.

7. Cleaning floors: Add vinegar to your mop water (diluted with water) to clean and disinfect hard floors. However, avoid using vinegar on natural stone floors like marble or limestone, as the acid can damage them.

8. Removing stickers and adhesives: Soak a cloth or sponge in vinegar and apply it to stickers or adhesive residue to help loosen them for easier removal.

Remember to always test vinegar solutions on a small, inconspicuous area before using them on a larger surface, especially on delicate materials. Additionally, while vinegar is generally safe to use, avoid using it on certain surfaces like granite countertops or hardwood floors, as it can cause damage.

What is NOx and SOx ?

Air Pollutants

In general, air pollutants are divided into two main groups: gases and particulate matters. The gases include Carbon Monoxide, nitrogen oxides (NOx), sulfur oxides (SOx), and Hydrocarbon. On the other hand, the particulate matters include dust, smoke, smog, and soot. The National Air Pollutants Emission data provides the emission data of air pollutants such as SOx, NOx, Carbon Monoxide, TSP and Volatile Organic Compounds that cause harm to human and the environment.

Air Pollutants Emission data

As the most basic data needed to establish the national environmental policy in securing clean air, air pollutants emission data provides the data on types, sources and the amounts of air pollutants. With this regard, In regard to this, the National Institute of Environmental Research is in charge of estimating the national air pollutants emission each year and managing the data as the nation's official statistics.

Sulfur oxides (SOx)

Sulfur compounds, which are prevalent in fuels, combine with oxygen when fuels are burned, and produce SOx gases in the atmosphere. When sulfur is oxidized, it forms sulfur dioxide or SO2. If it is more oxidized, it becomes SO3. These SO2 and SO3 are in the family of SOx. SO2 is easily oxidized in the atmosphere to SO3 and becomes sulfate, or reacts with water vapor to form micrometer-size droplets of sulfuric acid, H2SO4. SOx is a pungent, colorless gase that causes respiratory illness if concentrations reach a certain level. Even at the low level, however, it can be toxic enough to kill plants.

SOx, along with NOx, is mostly formed in the combustion of fuels containing sulfur such as coal and oil. SOx is responsible for the formation of acid rain, corrosion of metal structures and is harmful to people and other living organisms. Acid rain causes limited damage to any cities or industrial complexes, but the damage can spread across wide geographic areas if a large amount of acid rain is released. Acidification of lakes, surface waters, groundwater can do damage to aquatic creatures, forests and farming lands.

SOx reduction measures are divided into the precautionary measures and the post measure. The precautionary measures include the use of low sulfur fuels (low sulfur oil and coal) or clean fuels (natural gas and LPG) and the desulfurization of oil products. On the other hand, the post measure refers to exhaust gas desulfurization, a process to remove SOx gases from flue gas generated from combustion of oil and coal before releasing the gas from smokestacks. Exhaust gas desulfurization, however, has limitations in that this method can only apply to large-scale facilities due to the economic viability.

Nitrogen oxides (NOx)

NOx gases are emitted from high temperature combustion. Although most of the NOx gases are generated from the combustion of nitrogen present in the air, some are produced from the oxidation of nitrogen contained in fuels. Nitrogen generates various nitrogen oxides including nitrogen monoxide or NO, nitrogen dioxide or NO2, and Dinitrogen trioxide or N2O3. NO and NO2 are the most prominent nitrogen oxides and are often referred to as NOx. NO is easily oxidized to NO2, which is then dissolved in water to make HNO3. Like sulfur oxides, nitrogen oxides are the sources of acid rain.

NOx is harmful to human health. In direct way, it causes or worsens respiratory disease, and can do damage to plants, whereas it plays a significant role in photochemical reaction. N2O, or Nitrous Oxide, also known as laughing gas, is used as anesthetic, and is one of the air pollutants that cause global warming.

Volatile Organic Compound (VOC)

VOC means petrochemical products, organic solvent and other substances among hydrocarbons, and are notified by minister of environment in consultation with directors of relative executive agencies. VOC's steam pressure is over 0.02psi and its boiling point is under 100℃.

VOC is produced by organic combination of carbon and hydrogen and exists in diverse types. It is also generated by using oil product and incompletely incinerating oil, alcohol, and other organic acid. VOC includes Polycyclic Aromatic Hydrocarbons(PAHs) such as aldehyde, ketones, benzene, and benzopyrene, some of which is a carcinogen. In addition, many of VOC has a strong smell.

Photochemical reaction can be generated by mix of VOC and nitrogen oxides in the sunlight, causing pollutants including peroxyacetylnitrate. These pollutants can lead to visibility obstruction, eye disease, and respiratory disease, and damage to plants.

DUST

Dust means particles which are floating or scattering in the air. According to chemical composition and size of particles, dust has different influences on human health. The smaller a particle is, the worse effect it has on a lung. In addition, minute particles provide wide adhesion area, playing a role of vehicles for heavy metals, persistent organic pollutants, and endocrine disruptor. In general, diameter of particles in the air is from 0.001 to 500㎛ and particles of 0.1 to 10㎛ accounts for the largest portion. 1㎛ is 1/1000㎜ or 10000Å.

The density of dust in the air can be shown by the following units: TSP, PM10, and PM2.5. Total Suspended Particulate(TSP) means the total amount of dust scattering in the air, and PM10 indicates the amount of dust whose diameter is under 10㎛. Also, PM2.5 means the amount of dust whose diameter is under 2.5㎛.

CO

CO is produced by incomplete incineration of carbon. CO, which is colorless and odorless, can cause toxication and can be fatal only by a small quantity. When a man inhale CO, it joins with Hb in blood instead of O2, producing CO-Hb. Because CO is 200times powerful to combine with Hb than O2 it reduces the capability of conveying O2 by Hb. Main causes are heating and auto exhaust.

Physical characteristics of water at the atmospheric pressure

At atmospheric pressure, water exhibits several physical characteristics that are commonly observed under normal conditions:

1. State of Matter: Water exists predominantly in the liquid state at atmospheric pressure and temperatures typically encountered on Earth's surface (0°C to 100°C). However, it can also exist as a solid (ice) below 0°C and as a gas (water vapor) above 100°C.

2. Boiling Point: At sea level, where atmospheric pressure is approximately 101.3 kilopascals (kPa) or 1 atmosphere (atm), water boils at 100°C (212°F). This is the temperature at which the vapor pressure of water equals the atmospheric pressure, causing it to change from liquid to gas.

3. Freezing Point: Water freezes into ice at 0°C (32°F) at atmospheric pressure. At this temperature, the molecules in the liquid phase lose enough thermal energy to form a solid lattice structure, resulting in the solidification of water molecules into ice.

4. Density: The density of liquid water is approximately 1 gram per cubic centimeter (g/cm³) at 4°C, making it denser than ice. However, water's density decreases as it approaches its freezing point, causing ice to float on liquid water.

5. Surface Tension: Water molecules exhibit cohesive forces, resulting in surface tension, which causes the surface of water to behave like an elastic membrane. This property allows water droplets to form spherical shapes and enables certain insects to walk on the water's surface.

6. Specific Heat Capacity: Water has a relatively high specific heat capacity, meaning it can absorb and store a large amount of heat energy compared to many other substances. This property helps regulate temperature variations in the environment and contributes to the moderating effect of large bodies of water on climate.

7. Viscosity: Water has a relatively low viscosity compared to other liquids, meaning it flows relatively easily. However, its viscosity can increase with temperature and pressure changes.

8. Refractive Index: The refractive index of water is approximately 1.333 at room temperature, causing light to bend when passing from one medium (e.g., air) into water. This property is responsible for phenomena such as the apparent bending of objects viewed through water and the formation of rainbows.

These physical characteristics of water at atmospheric pressure play crucial roles in various natural processes, industrial applications, and everyday activities.

Pressure:	Atmospheric pressure at 1,01325 bar, i.e. normal atmospheric pressure on the sea level at 0°C.
Density:	Ratio of the mass of water (kg) occupied in a volume of 1 m3.
