A pelton wheel works at the foot of a dam because of which the head available at the nozzle is 400m. The nozzle diameter is 160mm and the coefficient of velocity is 0.98. The diameter of the wheel bucket circle is 1.75 m and the buckets deflect the jet by 150. The wheel to jet speed ratio is 0.46. Neglecting friction,
determine
(a) hydraulic efficiency,
(b) its speed and
(c) the power developed by the turbine.
We have a reciprocating compressor operating at 800 rpm. Suction pressure and discharge pressure are held constant by other systems that have nothing to do with the compressor. W
