Copper spheres of 20-mm diameter are quenched by being dropped
into a tank of water that is maintained at 280 K. The spheres may
be assumed to reach the terminal velocity on impact and to drop
freely through the water. Estimate the terminal velocity by
equating the drag and gravitational forces acting on the sphere.
What is the approximate height of the water tank needed to cool the
spheres from an initial temperature of 360 K to a center
temperature of 320 K?
