(2) A water main on Warren Street suddenly springs a leak, and you estimate the geyser reaches
about 20 feet in height. You further estimate that about 300 gallons per minute is leaking
based on the water flowing in the gutter. About how big is the hole in the water pipe?
(3) The geyser "Old Faithful" in Yellowstone National Park rises about 32 m upon eruption.
Estimate the velocity of the water at the ground surface.
