TURBINE IMPULSE - PELTON WHEEL
QUESTION 1:
The nozzles of a 4-jet Pelton wheel turbine, each have a diameter of 125 mm and the velocity of each water jet is 96 m/s. The available head at the nozzles is 500 m. The blade velocity is 46% of the jet velocity. The turbine has a hydraulic efficiency of 85% (i.e. nozzles included). The friction across the buckets is 6% from entry to exit.
