n drops of water
A space 2.5 cm wide between two large plane surfaces is filled with oil. Force required to drag a very thin plate of area 0.5 m ^ 2 just midway the surfaces at a speed of 0.5 m/sec is 1 N. The coefficient of viscosity in kg s/m^ 2 is:

A plate of area 2m^(2) is made to move horizontally with a speed of 2m//s by applying a horizontal tangential force over the free surface of a liquid. If the depth of the liquid is 1m and the liquid in contact with the bed is stationary. Coefficient of viscosity of liquid is 0.01 poise. Find the tangential force needed to move the plate.
