Question
Transcribed Image Text:A Kaplan turbine operates at (45 rpm) with a blade peripheral velocity of (14 m/s).
The hub to tip diameter ratio is (0.5). The inlet blade tip has zero
angle with the axial
direction while the inlet guide vane and outlet blade angles are (30°) and (22º)
respectively. If the specific speed is (130), find the overall efficiency of the turbine.
