Answer / Solution

UNSOLVED

State Newton`s law of viscosity and hence deduce the dimensions of the coefficient of viscosity.

Answer / Solution

UNSOLVED

In an experiment to determine the coefficient of viscosity of motor oil, the following measurements are made;

• Mass of galss sphere =1.2x10^-4kg
• Diameter of sphere = 4.0x10^-3m
• Terminal velocity of sphere=5.4x10^-1ms^-1
• Density of oil =860kgm^-1

Calculate the coefficient of viscosity of the oil.
