The overall efficiency of a reaction turbine is the ratio of

A Actual work available at the turbine to the energy imparted to the wheel
B Work done on the wheel to the energy (or head of water) actually supplied to the turbine
C Power produced by the turbine to the energy actually supplied by the turbine
D Actual work available at the turbine to energy imparted to the wheel

Correct Answer: Actual work available at the turbine to the energy imparted to the wheel

The overall efficiency of any turbine will be mechanical efficiency * hydraulic efficiency.
