Question
Water at 10°C flows through the system shown in the figure below at 0.40 m/s. Energy loss in the 40-cm pipe is
negligible. Energy loss in the 30-cm pipe is known to be 1.5V². A mercury manometer indicates that the absolute
pressure at the top of the 30-cm pipe is 749.5 mm Hg abs. The pressure of the surroundings is 101,330 Pa. Calculate the
power input to the pump.
