The velocities of the water at the entrance and at the exit of a hydraulic turbine are 10
m/sec and 3 m/sec, respectively. The change in enthalpy of the water is negligible. The
entrance is 5 m above the exit. If the flow rate of water is 18,000 m 3 /hr, determine the
power developed by the turbine.
