The coefficient of viscosity `eta` of a liquid can be defined from the equation

The coefficient of viscosity for hot air is

Coefficient of viscosity of a gas

When a solid moves therough a liquid, the liquid opposes the miotioon with a force F. The magnitude of F depends on the coefficient of viscosity eta of the liquid, the radius r of the sphere aknd the speed v of the sphere. Assuming that F is proportional to different powers of these quantities, guess a formula for F using the method of dimension.

Unit of coefficient of viscosity is

Units of coefficient of viscosity are

Coefficient of viscosity of a liquid does not depend upon "_____"

In dimension of circal velocity v_(0) liquid following through a take are expressed as (eta^(x) rho^(y) r^(z)) where eta, rhoand r are the coefficient of viscosity of liquid density of liquid and radius of the tube respectively then the value of x,y and z are given by
