Civil Engineering - Water Supply Engineering - Discussion

Axial flow pipes are used in water supply mains where head required is low and very high flow rates such as water supply mains.

Most commonly pump used for water supply is an axial flow pump.

It's a centrifugal pump not axial.

The most commonly adopted pumps in water supplies are --> centrifugal pumps.

Pumps commonly used for lifting of water supply main is --> Axial flow pump.

For lifting water in water supply mains, axial flow pumps.

While lifting wastewater in waster mains, reciprocating pumps are used.

Answer is A.

Explanation: An axial flow pump, or AFP, is a common type of pump that essentially consists of a propeller in a pipe. The propeller can be driven directly by a sealed motor in the pipe or mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.

Fluid particles, in course of their flow through the pump, do not change their radial locations since the change in radius at the entry (called 'suction') and the exit (called 'discharge') of the pump is very small. Hence the name "axial" pump.

Submersible pumps include axial flow pumps.

Centrifugal pumps are used because it gives continue discharge.

Centrifugal pump is the right answer because it has high discharge with low head.

Axial flow pump is a type of a centrifugal pump.
