In the test of the reaction turbine, the water flowing over the weir in the tailrace was found to be 39.8 ft3 /s. The leakage into the tailrace was found to be 1ft3 /s. The elevation of the centerline of the shaft above, the surface of tailwater was 12.67ft. The diameter of the turbine intake was 30in and the pressure at this section was measured by a mercury U-tube. The readings in the two sides of the mercury U-Tube were 10.556 ft and 0.900 ft, the zero of the scale being at a level 3.82ft below that of the centerline of the turbine shaft. The generator output was 391.8 kW, friction and windage loss 13.8 kW, iron loss 2.0kW and armature loss of 4.4kW. The specific gravity of the mercury used was 13.57. Calculate the efficiency of the turbine.
