A vertical draft tube is installed on a Francis Turbine and the total head to the center of the spiral casing at the inlet is 38 meters and velocity of water at the inlet is 5 m/s. The discharge is 2.1 cubic meters/second. The hydraulic efficiency is 0.87 and overall efficiency is 0.84. The velocities at the inlet and exit of the draft tube are 5 m/s and 1.5 m/s respectively. The top of the draft tube is 1 m below the center line of the spiral casing while the tailrace (water) level is 3 meters from the top of the draft tube. There is no velocity of whirl at either top or bottom of the draft tube and leakage losses are negligible. What is the power output of the turbine in kw? [20%] 987.8 901.3 746.9 832.6 632.9
