Two liquids of densities d1 and d2 are flowing in identical capillary tubes uder the same pressure difference. If t1 and t2 are time taken for the flow of equal quantities (mass) of liquids, then the ratio of coefficient of viscosity of liquids must bed1t1d2t2t1t2d2 d1t2t1d1t1 d2t2−−−−√

Two metal spheres of densities in the ratio 3:2 and diameter in the ratio 1:2 are released from rest in two vertical liquid columns of coefficient of viscosity in the ratio 4:3. If the viscous force on them is same, then the ratio of their instantaneous velocities is

A viscous fluid is flowing through a small tube at a rate of 0.200 m3/s. If the pressure difference across the tube is doubled, and the length of the tube is halved, and the radius is also doubled, then what is the new rate of flow of the fluid?

If two liquids A (PºA =100 torr) and B (PºB = 200 torr) are completely immiscible with eachother, each one will behave independently of the other, are present in a closed vessel. The totalvapour pressure of the system will be:

If two liquids of same mass but different densities r1 and r2 are mixed, then density of mixture is given by

Viscosity is the resistance to flow.Group of answer choicesTrueFalse
