If you move your finger in castor oil you would feel some dragging force against your moving finger. This is due to the viscous nature of the fluid. Same way if a small steel ball falls through castor oil kept in a jar then there will be a dragging force opposing the falling ball. This force is got by the formula 6 pi a eta v. Here pi is 3.14 and a - the radius of the ball. eta - the coefficient of viscosity of the castor oil and v - the velocity of the ball. This is known as Stokes's law of coefficient of viscosity.

Why different sized metal spheres used in determining the coefficient of viscosity of oil?
as according to stoke's law the terminal velocity depends upon the radius of the metal sphere.
What is damping coefficient of fluids?
I wanted to know what damping was not answer it!!!
What is Einstein law of viscosity?
Einstein's law of viscosity is stated by the equation u = 1 + 2.5 (volume fraction of solid particles). This equation is only used to calculate the relative viscosity of a slurry of fine particles in low concentrations.
How do you determine co-efficient of viscosity of pure liquid?
First of all, you have to break it apart. What is Viscosity?=thickness, stickyness, how it moves. To measure the thickness, you can either slide something down a slanted platform, or drop a marble into each jar of the liquids that you are comparing. To measure the stickyness, it would be a good idea to put cardboard on the two sides of the liquid, and stretch them apart, and see what happenes. Lastly, to measure how it moves: try and poor the liquids you are trying to compare down a slanted platform, and see how it moves.There isn't really something that can measure exact levels of viscosity.In conclusion, you can't get exact measurements of viscosity, but you are able to find out which liquid has the most viscosity, and which one has the less.Viscosity is the measure of fluidity a liquid exhibits - meaning how thick or how thin it is.Viscosity of liquid newtonian substances can be measured by measuring the time a liquid moves in a graduated tube from Point A to Point B at a given temperature usually 20oCCollodial substances can be measured using a graduated cup. The time taken for the liquid to drain out of the cup. the end time taken when the liquid stream breaks.In dilute solutions, an Ubhellode Tube is used. Here again, the time taken for a volume of liquid to pass from Point A to Boint B.In polymer melts, viscosity (melt viscosity) is done by measuring the torque of a synchronised stirrer in the molten polymer at a certain temperature.

What is the difference between Newtonian and non-Newtonian fluid?
Water is an example of a Newtonian fluid. Non-Newtonian fluids include catsup, paint, liquid detergent, liquid polymers and a variety of other liquids. In a Newtonian fluid, the relation between the shear stress and the strain rate is linear, the constant of proportionality being the coefficient of viscosity. In simple terms, the size of the drops is directly related to the thickness of the fluid, all else being equal. In a non-Newtonian fluid, the relation between the shear stress and the strain rate is nonlinear, and can even be time-dependent. Therefore a constant coefficient of viscosity can not be defined. Multi-viscosity motor oil, which changes viscosity with temperature, is a common example. Newtonian fluids obey Newton's laws.but non Newtonian fluids does not obey Newton's laws.
How do you calculate viscosity from a stokes law graph?
Hmmm.. what is "stokes law graph" ? If Stokes Force = Fs, r=radius of a tube, v=velocity of a particle The formula of viscosity is Fs=6.pi.viscosity.r.v Then viscosity= Fs/(6.pi.r.v)
Can we measure the coefficient of viscosity of mercury by using stoke s law?
Yes, the coefficient of viscosity for Mercury can be calculated using Stoke's Law.
How the coefficient of viscosity of a liquid changes with temperature?
The coefficient of viscosity of liquids decreases with an increases in temperature.
What is the value of coefficient of viscosity of caster oil?
0.2
What is the coefficient of viscosity of glycerin?
0776 N S/m2

Define suspending agents?
Suspending agents help lower sedimentation rate of particles in suspension. This works by increasing viscosity of liquid vehicle, and slowing down settling in accordance to Stokes Law.
What is damping coefficient of fluids?

What is the coefficient of viscosity?
A measure of the resistance to flow of a fluid under an applied force.
What is a centistroke?
The correct spelling is centistoke. The ratio of a absolute viscosity of a liquid in centipoise to the density. It is a cgs unit of kinematic viscosity in customary use that is one hundredth of a stokes.
Si unit of coefficient of viscosity?
The Si unit for viscosity is Pa·s = kg/(s·m).
What is the viscosity of asphalt?
Viscosity - The ratio between the applied shear stress and the rate of shear is called the coefficient of viscosity.This coefficient is a measure of the resistance to flow of the liquid. It is commonly called the viscosity.The SI unit of viscosity is the Pascal second (Pa•s). Another common unit of viscosity is the centipoise (cP) where 100 cP is equal to 1 Poise (P), and 10 P = 1 Pa•s.
