Which of the following efficiencies for Kaplan Turbine is defined as the ratio between the power available at the shaft to the power supplied by water at the inlet?

Which of the following efficiencies for Kaplan Turbine is defined as the ratio between the power available at the shaft to the power supplied by water at the inlet? Correct Answer Overall efficiency

The definition of Overall efficiency in a Kaplan turbine states that it is the ratio between the Shaft power to the Water power. Hence, the correct option is Overall efficiency.
