What is terminal velocity? Discuss the factors on which it depends.

Using dimensional method obtain, Stoke’s law expression for viscous force F = 6pi eta anu .

The terminal velocity of a rain drop is 30cm//s . If the viscosity of air is 1.8xx10^(-5)Nsm^(-2) .The radius of rain drop is

Define terminal velocity. Show that the terminal velocity upsilon of a sphere of radius r, density rho falling vertically through a viscous fluid of density sigma and coefficient of viscosity eta is given by upsilon = 2 / 9 ((rho - sigma)r^2 g) / eta Use this formula to explain the observed rise of air bubbles in a liquid.

Assertion : Terminal velocity is same as the critical velocity. Reason : The constant velocity of fall of a body through a viscous fluid is called terminal velocity.
