Draw and explain performance and operating characteristics curves of a Pelton turbine 
by

1 Answer

Answer :

The followings are the important characteristic curves of a turbine : Main Characteristic Curves or Constant Head Curve. ... The speed of the turbine is varied by changing load on the turbine. For each value of the speed, the corresponding values of the power (P) and discharge (Q) are obtained.
