why reduce viscocity in crude oil?

Yes, it pumps easier which makes the pump motor use less power, which saves $$$$... Plus, it doesn't tend to plug up instruments & valves like the thicker stuff does.

When a fluid (liquid or gas) flows over a surface there is some amount of friction between that fluid and the surface. As a result the velocity of the fluid on the surface is zero. As you move away from the surface the velocity increases until it reaches the same velocity as the rest of the fluid flow. This small region where the velocity of the fluid increases from zero up to the velocity of the rest of the flow is called the boundry layer.\n\nIf a fluid is more viscous this boundry layer will be thicker. Lower viscosity means a smaller boundry layer.

I don't think so...may appear that way but it is probably only fluid that you are decreasing.  Sorry...you have to do it the old fashioned way =)

A major tool in exploration is images made from the reflections of sound waves from surface explosions.  Analysis of these images is what helps explorers figure out the existence and location of oil and gas reserves.  Any improvement in the image processing and pattern recognition would help reveal overlooked sources and deeper sources, and would reduce the waste of drilling to a false image.\n\nOn the production side, refining crude oil into its various products safely and efficiently is a set of extremely complex and sensitive chemical processes.  Some really good visualization of these processes could help run an individual refinery smoothly, efficiently, and safely, and could also help reveal parts of the process which could be improved.  The human brain has tremendous pattern recognition capability with data presented to it visually.\n\nAs an industry outsider, that's all I know.

yes, the more the  intermolecular distance the more will be viscousity , it means it will be more compressible. Likewise diffusion and surface tension- It is very much clear that diffusion is proportional to inter-molecular distance.

through a process called "Cracking"\nthis is when you take a larger molecule and crack it into smaller more volatile molecules\nthey use this in oil refineries to turn crude oil into more valuable products

15w-40 has a cold cranking wieght of 15... (w for winter) and is a 40 weight at operating temp, so it'll flow a little better then the 20w-40. Synthetic oils usually come in a wider range of viscositys like 0w-30, 5w-40 and such. Takes alot... too much volume index improvers and such for conventional, that the oil would go out of grade in no time... different manufacturers have a small difference in wieghts... one may be a high 40 wieght, the other a low 40 weight at operating temp. Just sticking with name brands insure quality.

well, others might have told you it is pressure, and actually even i would have gone for it!\nbut since you have mentioned in particular on a fluid, then this ratio can also be called as Bulk's modulus(though this applies even to solids)\nit can also be the coeff of viscosity taken velocity gradient times\nthere can be various other depictions also

this question may appear ambiguous to the inexperienced. the question asks for an explanation for the decrease, which implies the asker's initial expectation for an increase. the questioner assumed that viscosity increased with ethanol concentration, but facts led to the conclusion that this trend is only obeyed up to the 40% conc level, after which viscosity decreases with ethanol concentration.\n\nwhy the bell curve? that is what you are supposed to answer, Radagast.\n\n40% ethanol (w/w in water, which is the obvious solvent) happens to be the point at which there is a certain ratio of ethanol to water molecules. this special ratio is apparently the point at which there are maximum interactions (H-bonding) between ethanol and water such that the fluid becomes more viscous than water or ethanol alone.\n\nby increasing ethanol conc from 0-40% you will thus see an increase in viscosity. after 40%, the ratio of water molecules apparently increases, so the fluid viscosity will tend toward the viscosity of ethanol (which is still higher than pure water).\n\nusing arbitrary values, viscosity starts at 1 for pure water, increases to 10 for 40% ethanol, then decreases to 2 for 100% ethanol.

One very important application for viscosity that affects much of the world is the rating of engine oils.  For example 10W30 engine oil behaves as though it has a low viscosity (10) while cold during startup but thickens due to the action of special polymers when hot (30).  This increases the flow of cold oil improving initial lubrication while reducing engine wear.  The specific oil viscosity grade selected may depend on the season and the minimum temperature expected (especially where bitterly cold).  This can be an important safety consideration allowing a sure start when the battery exhibits minimum power, preventing people from being stranded in the cold.  When I worked at Brookfield Engineering (long ago) they shipped viscosimeters all over the world for use in chemical plants including paint factories.

When surfaces are rubbed against each other, friction causes resistance that must be overcome by power.  The power used to overcome friction produces heat, especially at the microscopic level (atoms and molecules) that can weaken the material or even destroy it.  Rapidly moving parts (such as in an engine) create much more heat than slow moving parts such as the front wheel bearings of a car.  Within the engine, oil is circulated to all moving parts to make them slippery (reducing friction), remove heat from friction (and combustion heat) to an oil cooler and to remove sediment and any steel chips to the oil filter.  In the wheel bearing, grease (a mixture of soap and oil) reduces friction and the airstream of the moving car is enough to remove any heat produced.\n\nBTW, ball bearings are often used to convert sliding friction to rolling friction greatly reducing heat but still requiring cooling oil and lubrication within the engine.  In many pumps, there is sliding friction in the pump sleeve bearings but the bearings are lubricated and cooled by the fluid being pumped.

Crude oil is composed of a mix of molecules composed of hydrogen, carbon, and oxygen atoms in many different forms. These can range from simple compounds like methane (CH4) or ethane (C2H6) to long complicated molecules such as paraffins like C8H18, also known as octane that is used to rate motor fuels. \n\nThe initial source of the crude oil is the accumulation of the dead bodies of phytoplankton and zooplankton which are microscopic plants and animals that live in the sea and fresh water lakes. Adding to this organic matter that accumulates on the sea floor is the material that is carried into the ocean by rivers, such as pollen, spores, and plant material. To be preserved, all of this organic matter must fall into a zone of the water that is low in oxygen, otherwise it will decay rather than be preserved. Mud and silt coming from rivers will often bury this material before it can be consumed by living organisms. Near the mouths of rivers there are often rapid rates of deposition of mud and silt that will bury organic material, and over time it may be buried by several miles of sediment. For example, the Mississippi River Delta, which is a prolific oil producing area, has deposited sediments several miles thick over the last 66 million years. \n\nAs these deposits of organic matter are buried deeper and deeper they begin to warm from the heat of the earth's interior. When they reach a temperature of about 140 degrees F, they begin to undergo "catagenesis" which is a molecular change that makes oil. If they reach a temperature of about 250 degree F, they will begin to form more natural gas than oil. If they get too hot it is possible to change them to graphite, and no oil or gas will be produced. \n\nIn other types of depositional environments the plants and animals that become oil also form the rock. Carbonate mudstone (which is simply a type of limestone) of the Hanifa Formation in the Middle East formed much of the oil in Saudi Arabia. These carbonate mudstones  are composed of huge accumulations of lime muds made from the breakdown of marine algaes and other organisms. These deposits of the remains of marine organisms also must undergo burial and and heating by the deep earth to generate oil and gas. \n\nSo when you burn oil, you are really burning solar energy that was stored by plants and animals thousands or millions of years ago and buried in the earth. \n\nEvery time I answer this question someone comes along and points out that there may be oil that is not from living organisms. Thomas Gold, a respected physicist at Cornell proposed that oil may be abiotic; that is just another type of deposit of the earth. This may in fact be possible, but if it is, it is likely to be a very minor source of the oil on Earth. The reasons are complicated, but the fact that the rocks where Gold predicted this abiotic oil should be found do not contain oil is pretty conclusive proof that this type of oil is not significant, if it exists at all. \n\nHere is my previous answer to this question:\nhttp://answers.yahoo.com/question/;_ylt=AqkzP9amgCudYabOz20w2YIjzKIX?qid=1006022109950

It is the fluid like stress before it hardens.  It is important for use in designing form works so they don't blow out.  It is more than double that of water.

In my opinion if the lubricant had a viscosity of 5 percent less then the original i would change the oil.
