  • A Kaplan turbine working under a head of 81 5 m is dis-
    charging 295 m%/sec. of water at 75 R.P.M. and developing 38,000
    B.H.P.
    The runner dia is 7 m and boss diameter is 3 m.
    Determine (2) the inlet and outlet blade angles of runner, (i)
    mechanical efficiency and (in) overall efficiency.
    Assume hydraulic efficiency as 94%
