During the flow of 200 ft 3 /s of water through the hydraulic turbine shown, the pressure indicated by gage A is 12 psig. What should gage B read if the turbine is delivering 600 hp at 82% efficiency?...

During the flow of 200 ft³/s of water through the hydraulic turbine shown, the pressure indicated by gage A is 12 psig. What should gage B read if the turbine is delivering 600 hp at 82% efficiency? Gage B is designed to measure the total pressure, that is,
 for an incompressible fluid.
