2. A Francis turbine is installed with a vertical tube. The pressure gage located at the penstock leading to the turbine casing reads 372.6 kPa, and velocity of water at the inlet is 6.0 m/sec. The discharge is 2.5 m3/sec. efficiency is 85% and the overall efficiency is 82%. The top The hydraulic of the draft tube is 1.5 m below the center line of the spiral casing while the tail race level is 2.5 m from the top of the draft tubo. or bottom of the draft tube and leakage losses are negligible. There is no velocity of whirl at the top Calculate the following: 7 : a. The total head on the turbine in meters. b. The power output of the plant in KW. c. The mechanical efficiency of the turbine. 2. A Francis turbine is installed with a vertical tube.
