- A turbine is rated at 600hp when the flow of water through it is 82cu.m/sec. Assuming an efficiency of 92%, what is the head acting on the turbine?Paolo owns a hydroelectric power generating system as shown in HG008. Water flows from an upper reservoir to a lower one passing through a turbine at the rate of 150 lps. The total length of pipe connecting the two reservoir is 100 m.
