For a Kaplan turbine with runner diameter 4m, the discharge is 60 m³/sec and hydraulic and mechanical efficiency are stated to 90% and 94 % respectively. The diameter of the boss is 0.3 times the runner diameter and the speed ratio are 2.Assuming the discharge is free and there is no swirl at outlet calculate the net available head on the turbine, the power developed and specific speed.
