Problem
A ball of density 3500 kg m−3 and radius 6.0 mm is released from rest in a liquid of density 920 kg m−3 and viscosity 0.70 Pa s .
(1) What is the terminal speed of the ball as it falls through the liquid? Ignore the buoyant force.
(2) How do you expect the answer to a to change if the liquid temperature is increased?
(3) Repeat a taking the buoyant force into account.
