During a flow of 500 liters, the gage pressure is 68 kPa in the horizontal 300 mm supply line of a water turbine. A 41 kPa vacuum is measured at a 450 mm section of draft tube 2 m below the turbine. Assuming an efficiency of 85%,
a. Compute the total head extracted by the turbine.
b. Compute the output horsepower of the turbine.
c. Compute the input horsepower of the turbine.
