Physics : Properties of Matter - Solved Example Problems for Viscosity

EXAMPLE 7.9

A metal plate of area 2.5×10-4m2 is placed on a 0.25×10-3m thick layer of castor oil. If a force of 2.5 N is needed to move the plate with a velocity 3×10-2m s-1, calculate the coefficient of viscosity of castor oil.

Given: A=2.5×10-4 m2dx = 0.25×10-3mF=2.5and dv = 3×10-2 m s-1
