Power required to drive a centrifugal pump is directly proportional to __________ of its impeller.

The mechanical efficiency of an impulse turbine is

The overshot water wheels are those in which the wheel runs entirely by the __________ of water.

In a Kaplan turbine runner, the number of blades are generally between

If H_{g} is the gross or total head and h_{f} is the head lost due to friction, then net or effective head (H) is given by

Discharge of a centrifugal pump is

A Pelton wheel develops 1750 kW under a head of 100 metres while running at 200 r.p.m. and discharging 2500 litres of water per second. The unit power of the wheel is

The static head of a centrifugal pump is equal to the __________ of suction head and delivery head.

The ratio of actual work available at the turbine to the energy imparted to the wheel is known as __________ efficiency.

Geometric similarity is said to exist between the model and the prototype, if both of them
