Question: Consider the situation described in Problem 8.35. If the pump exit diameter is 50 mm, determine the ratio of the pump power to the kinetic

Consider the situation described in Problem 8.35. If the pump exit diameter is 50 mm, determine the ratio of the pump power to the kinetic energy rate of the exiting water.

Problem 8.35

Water enters a pump at 300 K and 150 kPa and exits at 200 kPa with a flow rate of 3.5 kg/s. Estimate the shaft power required to pump the water at these conditions. Neglect all friction and heat-transfer effects. Assume the temperature of the water at the exit is approximately 300 K and regard the water as incompressible.
