The radial clearance between a plunger and the cylinder wall is 0.1 mm. The length
of the plunger is 0.3 m and the diameter is 100 mm. Calculate the velocity and the rate
of leakage past the plunger at an instant when the difference of pressure between the
two ends of the plunger is 9.2 m of water. Absolute viscosity = 1.31 x10 -3 kg/m-s.
