1. A hydraulic turbine generates 50, 000 hp at 75 rpm with a head of 100 f t. Find the specific speed and use Figure 12.16 to determine what type of turbine is being used. 2. A hydraulic turbine operates at a specific speed of 100 (U.S. customary units) and delivers 500 kW with a head of 10 m. What type of turbine is being used, and what is the rotational speed necessary to give the optimum efficiency? 3. When it operates at peak efficiency, a turbine delivers 25, 000 hp at a speed of 450 rpm with a head of 4500 f t. What type of turbine is being used? Estimate the flow rate and the size of the machine, assuming there are no losses in the flow upstream of the turbine.
