A piston 113 mm diameter and 150 mm long has a mass of 9 kg. It is placed in a vertical cylinder 115 diameter containing oil of dynamic viscosity 0.12 Pa · s and relative density 0.9 and it falls under its weight. Assuming that piston and cylinder are concentric, calculate the time taken for the piston to steadily through 75 mm
