Front 18

Centrifugal pump

Back 18

In a centrifugal pump energy is imparted by centrifugal force. Force is created by rotation of an object. The force drives outward from the centre of rotation.

5 principles of friction loss

Back 30

Varies directly with length of hose

For the same velocity, Decreases with increase in diameter

Increases directly as the square velocity (m/s)

Increases with roughness of hose

Independent of pressure

Front 31

Reduce friction loss by:

Back 31

Eliminate sharp bends

Use adapters only when necessary

Keeling branches and valves fully open

Use proper size gaskets

Use short lines when possible

Use large hoses or multiple lines
