A square metal plate 1.5 m side and 1.5 mm thick weighing 50 N is to be lifted through a vertical gap of 25 mm of infinite extent. The oil in the air gap has a specific gravity of 0.95 and viscosity of 2.5 N.s/m. If the metal plate is to be lifted at a constant speed of 0.1 m/s find the force and power required. [Ans. 145.7 N, 14.57 W]
