A Francis turbine is installed with a vertical draft tube. The total head to the center of the spiral casing at the inlet is 60 m and the velocity of water at the inlet is 7.5 m/s. The discharge is 1.5 m^3/s. The hydraulic efficiency is 0.87 and the overall efficiency is 0.84. The vertical distance from the centerline to the top of the draft tube is 1.5 m while the tailrace water level is 2.5 m from the top of the draft tube. What is the total head on the turbine in meters?
