![A differential thermocouple with sensors at the inlet and exit of a pump indicates that the
temperature of water rises 0.048°F as it flows through the pump at a rate of 1.5 ft³/s. If
the shaft power input to the pump is 23 hp and the heat loss to the surrounding air is
negligible, determine the mechanical efficiency of the pump. We take the density of
water to be p = 62.4 lbm/ft3 and its specific heat to be c = 1.0 Btu/lbm.°F. s]
