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

The coefficient of viscosity eta of a gas depends on mass of the gas molecule, its effective diameter and its average speed. It is known that diameter of helium atom is 2.1xx10^(-10) m and its coefficient of viscosity, at room temperature is 2.0 xx 10^(-5) kg m^(-1)s^(-1) . Estimate the effective diameter of CO_(2) molecule if it is known that eta at room temperature for CO_(2) is 1.5 xx 10^(-5) kg m^(-1)s^(-1) .

The relationship between the coefficient of viscosity of a liquid and temperature can be expressed as

Assertion : Water flows faster than honey. Reason : The coefficient of viscosity of water is less than honey.

The coefficient of viscosity n of a fluid moving steadily between two surfaces is given by the formula, f = nA(dV)/(dx) where f is the frictional force on the fluid, A is an area in the fluid and dV//dx is the velocity gradient inside the fluid at that area. The SI unit of viscosity coefficient n is given as.
