Evaluate resultant force on the bucket, Mechanical Engineering

Assignment Help:

A single jet pelton wheel runs at 300 rpm under a head of 510 m. the jet diameter is 200m, its deflection inside the bucket is 165o and its relative velocity is reduced by 15% because of friction Evaluate :

(i) Water horse power.

(ii) Resultant force on the bucket.

(iii) Brake power if mechanical losses are 3% of power supplied, and overall efficiency.

Assume Kv (coefficient of velocity) 0.98 and Ku (speed ratio) 0.46.
