When water drains out of a hole in the bottom of a tank, the stream radius contracts as the speed of the water increases. Assume that the stream starts with zero water velocity at the top of the tank, at a height H above the hole, and ignore all instabilities that will lead to breakup of the stream (turbulence, etc.). Find the distance d beneath the hole at which the radius of the stream is 80% of the hole radius. [Ans: 1.44 H]
