Problem 09 Water flows steadily through a power plant. The enthalpy of the outlet water is the same as the enthalpy of the inlet water. The water inlet is 40 m above the water outlet. Both inlet and outlet are at atmospheric pressure. The inlet velocity is 9 m/s, and the outlet velocity is 15 m/s. The flow rate is 5000 kg/s. What is the power output of the plant?
