Viscosity | Viscous Drag Force on Flat Plate | Stoke's law: Terminal Velocity | Poiseuille's equation

A viscous force of 1.018 xx 10^(-7) N acting on a raindrop makes it fall through air with a terminal velocity of 1 ms^(-1) . If the viscosity of air is 0.018 xx 10^(-3) PI, what is the radius of the raindrop? Hint : Stokes' law

What do you mean by terminal velocity?

Rain drops fall with terminal velocity due to

A sphere of density rho falls vertically downward through a fluid of density sigma . At a certain instant its velocity is u. The terminal velocity of the sphere is u_0 . Assuming that stokes’s law for viscous drag is applicable, the instantaneous acceleration of the sphere is found to be beta(1-(sigma)/(rho))(1-u/(u_(0))) . here beta is in an integer. find beta .
