kinematic viscosity

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

2. What is the maximum diameter of a spherical particle of dust of density 2500 kg · m−3 which will settle in the atmosphere (density 1.225 kg · m−3, kinematic viscosity 14.9 mm2 ·s−1) in good agreement with Stokes’s Law? What is its settling velocity?
