For a hydroelectric plant, a hydraulic turbine-generator is installed at the site below the free surface. The turbine drives a generator for electricity.  The elevation difference between the two free surfaces is  . The power input from the fluid to the turbine is is . The shaft power output from the turbine is . (5) If the combined efficiency of the turbine and generator is , calculate the efficiency of the  generator,  ________%

22.The potential energy for 2,000 m3 of water stored in dam at a height of 20 m is.

Q3) Kaplan turbine A) The runner of Kaplan turbine working under dsitance of (5.5m) to produce (9 MW). Speed ratio and flow ratio are (2.08) and (0.68) respectively. Overall efficiency is (0.85). Find diameter and speed of the runner. The hub to tip runner diameter is (1/3). Q4) Design of Kaplan turbine to work under a head of (25m) and transfer (10 MW) power the diameter of hub and tip are (1.2m) and (3m) and overall and hydraulic efficiency are (0.85) and (0.9) respectively. Find the speed and angles of velocity triangles. Hint: The velocity triangle of inlet and outlet radial flow
