A solute dissolves in a solvent.
Because methanol is a very polar solvent
The viscosity is similar to the viscosity of water.
solvent for cellulose ether
It is a solvent used for production of paints.
Relative viscosity is defined as ratio of viscosity of solution to that of a pure solvent.
Relative Viscosity often refers to that of a Polymer Solution and is defined as the ratio of the viscosity of the solution to the pure solvent. It is calculated experimentally by measuring the time that it takes for the pure solvent to pass through a certain tube, in certain conditions , and comparing it with the time it takes for the solution to pass through the same tube, in the same condition. The term Apparent Viscosity is used when you calculate the viscosity of a non-Newtonian fluid by applying equations that are derived for the viscosity of a Newtonian fluid. So it is not the actual viscosity. I hope this answers your question.
As the engine wears, the bearing clearances become a little larger, REQUIRING that you use a higher viscosity oil to maintain oil pressure. If using the recommended oil viscosity results in low oil pressure, you should certainly switch to the 10W40. HOWEVER, if the engine can maintain oil pressure using the recommended oil viscosity, you will get better economy and the engine will perform better.
The oil reaches a temp too high to maintain viscosity capabilities. Usually higher than the operating temperature of a vehcile.
It is possible to calculate the diffusion coefficient of a liquid. You would set up a liquid-liquid diffusion coefficient sample. Use the variables W for solvent molecular weight, F for?æsolvent association factor, V for solvent viscosity, M for solvent molal volume, and T for system temperature.The equation you use is D(A,B) = [7.4T (FW) ^0.5]/ [V (M^0.6) * (10^8)].?æ

Yes. To thin, and to clean up, you will have to use a solvent.
Viscosity has to do with measuring the flows of liquids. It helps in absorbing drugs into the human body, and that is just one medical use of viscosity.
what products or foods use viscosity as part of advertising to get people to but it
It is a solvent.
A component of a solution is extracted by the use of a selective solvent for this component.
Normal plasma behaves like a Newtonian fluid at rates of shear. Typical values for the viscosity of normal human plasma at 37°C is 1.2Nsm-2. The viscosity of normal plasma varies with temperature in just the same way as does that of its solvent water, a 5°C increase of temperature in the physiological range reduces plasma viscosity by about 10%.
