Q.

The hydraulic efficiency of a reaction turbine, is the ratio of

  • APower produced by the turbine to the energy actually supplied by the turbine
  • BActual work available at the turbine to energy imparted to the wheel
  • CWork-done on the wheel to the energy (or head of water) actually supplied to the turbine
  • DNone of the above
Correct Answer : (C)

Work-done on the wheel to the energy (or head of water) actually supplied to the turbine

Hints :
Previous

According to Bernoulli's equation for steady ideal fluid flow

Next

A Francis turbine is used when the available head of water is
