4. (20 points) Figure on the right shows a hydraulic turbine designed to convert the kinetic energy of water into the mechanical shaft energy. Water enters the turbine, at the inlet, with the velocity V = 40m/sand the mass flow rate m = 1,000kg/s. Water exits the Vi-40s turbine with a negligible velocity, say, Vout = 0m/s. The efficiency of H20 HzO V Voudz0.% the turbine is 75 %. Potential energy and flow work can be ignored. 4a. (5p) Please calculate the specific kinetic energy of water entering the turbine (E or ke; in J/kg). 4b. (5p) Please calculate the rate of total kinetic energy of the water flow (E, or KE; in J/s or W) 4c. (5p) Please determine the mechanical power output of this turbine (W, in W or kW). out> 4d. (5p) Please determine how much mechanical energy would this turbine generate during an hour 4.
