Extracted text: For a Kaplan turbine with runner diameter 4 m, the discharge is 60 m/s and the hydraulic and mechanical efficiencies are stated to be 90 percent and 94 percent respectively. The diameter of boss is 0.3 times the runner diameter and the speed ratio is 2.0. Assuming that discharge is free and there is no swirl at outlet, calculate the net available head on the turbine, the power developed and specific speed.
