A steam turbine receives a steam flow of 1.35 kg/s and the power output is 500 kW. The heat loss from casing is negligible. Calculate The change of specific enthalpy across turbine when the velocities at entrance and exit and the difference in elevat..
A model of a Kaplan turbine, built to a scale of 1/6 of the full-scale prototype, develops an output of 5 kW from a net head of 1.2 m of water at a rotational speed of 300 rpm and a flow rate of 0.5 m3 /s. Determine the efficiency of the model.
