What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
What is the difference between fuel oil in ships and kerosene in jet engines?
fuel oil is used by faggets who are member of the dick circle where as kerosene is used by people with dicks coming out their ears
What is the difference between motor oils 5W30 10W30 20W50 and so on?
Let's start with understanding viscosity. Your owner's manual may tell you to use SAE 5W-30 engine oil. What does this mean? SAE stands for the Society of Automotive Engineers. They have created a standard for identifying the viscosity characteristics of engine oil. The 5W-30 part of the symbol is actually just a name. The W part of the name is an indicator of low temperature viscosity properties while the 30 part of the name is an indicator of the high temperature or operating viscosity properties. The numbers are just relative indicators to help the consumer. In other words, a 5W oil does not have a viscosity of 5, nor does a 30 weight oil have a viscosity of 30. What the numbers do mean is that the viscosity characteristics of a 5W oil are lower than that of a 10W oil. As well, a 30 weight oil has lower viscosity properties than a 40 weight oil. Its all very confusing, isn't it? The best thing to do is use the appropriate viscosity for your engine and climate as recommended by the manufacturer. In general, newer vehicles will specify lower viscosity oils such as 5W-30 while older vehicles will specify higher viscosity oils such as 20W-50. This is because today's engines are built with tighter bearing clearances to take advantage of the fuel economy benefits of lower viscosity oils. It is not really a good idea to use thicker oil in one of these engines because it will disrupt the oil flow characteristics of the engine and may create excessively high oil pressure. In an older engine that was designed with larger bearing clearances, it is appropriate and recommended to use a thicker oil to maintain proper oil pressure and provide adequate bearing film thickness. This is also true for engines that have a lot of miles on them and the oil pressure is starting to drop off. By using higher viscosity oil, you can boost the oil pressure back to normal levels and increase bearing film strength.
What fuels can be made out of crude oil?
Gasoline, jet fuel, kerosene, diesel for cars, and heating oil are the most common.
Is the same hydraulic oil for your car suitable for your boat?
no,because boat uses hydraulic oil of less viscosity.
What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
How is oil viscosity index calculated?
with a calculator
What is the viscosity index of palm oil?
..5
How would you define viscosity - index?
Viscosity index is a measure of how an oil's viscosity changes with temperature. Higher viscosity index oils are more resistant to changes in viscosity with temperature, making them perform more consistently across a range of temperatures.
How do you increase the viscosity of vegetable oil?
Cool it.
What is the range viscosity index for a SAE 40?
The viscosity index (VI) for an SAE 40 oil typically ranges from 95 to 115. This index measures how much the viscosity of the oil changes with temperature; a higher VI indicates that the oil maintains its viscosity better across temperature variations. SAE 40 oils are commonly used in applications requiring high-temperature performance, such as in certain engines and industrial machinery.
How do you Engine Oil?
Well Engine oil manufacturers keep the manufacturing techniques secrets with each others. Most motor oils are made from a heavier, thicker petroleum hydrocarbon base stock derived from crude oil, with additives to improve certain properties. The bulk of a typical motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule. One of the most important properties of motor oil in maintaining a lubricating film between moving parts is its viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow. The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index.

Name 3 oil additives and state the purpose of each?
Three oil additives include viscosity index improvers, alkaline compounds, and friction modifiers. Viscosity index improvers reduce changes at high temps, the compounds prevent acid erosion, and the modifiers form protective films on engine parts.
What will cause oil viscosity to decrease?
Factors that can cause oil viscosity to decrease include an increase in temperature, shearing forces from mechanical stress, contamination by fuel or other solvents, and oxidation or degradation of the oil over time.
What is the difference between single viscosity oil an mulit-viscosity oil?
Single viscosity is high quality oil. Mulit-viscosity oil is used for in the winter.
What happens when you mix coconut oil and kerosene?
No, coconut oil do not dissolve in kerosene
