Problem 3: A piston 10 cm in diameter and 50 cm in length moves coaxially in a cylinder
10.02 cm in diameter. The space between the piston and the cylinder is filled with oil of
kinematic viscosity 9.25x10 m²/s and specific gravity 0.88.

a) Assuming a linear variation in velocity, determine the force required to move the
piston at 0.5 m/s.
b) Determine the torque necessary to rotate the piston at 1200 rpm assuming.
