What is coefficient of viscosity .

Give the dimensional formula of coefficient of viscosity .

Write SI and CGS unit of coefficient of viscosity .

Discuss coefficient of viscosity in the contex of stress and strain .

L,M and T are units of length, Mass and Time respectively in a system of units In which of the following system, unit for coefficient of viscosity is 100 poiseuille

A small steel ball of mass m and radius r is falling under gravity through a viscous liquid of coefficient of viscosity eta . If g is the value of acceleration due to gravity. Then the terminal velocity of the ball is proportional to (ignore buoyancy)

If an experiment to measure coefficient of viscosity radius of tube measured r = (0.100 +- 0.001) cm and length 1 = (50.0 +- 0.1) cm and volume of fluid coming out of capillary in unit time is V = (0.25 +-0.01) cm//^(2) . If pressure difference between end of tube is p = 10^(6) dyne/ cm^(2) , then by using Poeisullie's law V=(pi pr^(4))/(8 eta l) Find coefficient of viscosity.

A layer of glycerine of thickness 1 mm is present between a large surface and small surface of area 0.1m^(2) . With what force the small surface is to be pulled, so that it can move with a velocity of 1 m/s ? (coefficient of viscosity =0.07g-m^(-1)s^(-1) )

In dimension of critical velocity v_(c) of liquid following through a tube are expressed as [eta^(x)rho^(y)r^(z)] where eta, rho and r are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively, then the values of x,y and z are given by

A bubble of air of diameter 0.2 cm rises up uniformly in water with a velocity of 200cm//s . If the density of water is 1gcm^(-3) , find coefficient of viscosity of water. Neglect density of air w.r.t that of water. (g=9.8m//s^(2))
