Pelton turbine is the only type that is mostly used these days. It is also called free jet turbine and operates under a high head of water and, therefore, it requires a comparatively less quantity of water. Estimate the Power available at the nozzle, horse power HP and the efficiency of the turbine under the following conditions: 1. Working head equal 40 meter. 2. mass flow rate at the water equal 750 liter per second 3. mean bucket speed of the wheel equal 14 meter per second 4. Jet is deflected by the buckets through an angle of (165°) and the velocity coefficient was (0.985).
