Water is siphoned from a large tank and discharges into the
atmosphere through a 2-in.-diameter tube as shown in the figure
below. The end of the tube is 3 ft below the tank bottom, and
viscous effects are negligible. Determine the volume flowrate from
the tank. Determine the maximum height, H, over which the water can
be siphoned without cavitation occurring. Atmospheric pressure is
