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

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

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

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

Discharge of a centrifugal pump is

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

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

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