A fountain sends a stream of water straight up into the air to a maximum height of 4.87 m. The effective area of the pipe feeding the fountain is 5.71 x 10-4 m2. Neglecting air resistance and any viscous effects, determine how many gallons per minute are being used by the fountain. (1 gal = 3.79 x 10-3 m3)
