Civil Engineering - Water Supply Engineering - Discussion

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.

Dynamic pressure pipe is two types:
1. Centifugal pump
2. Propeller pump (axil flow pump) both are used lifting of water with pressure. But most commnly used axil flow pump.

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.

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

Axial flow pumps are used in applications that require very high flow rates and very low amounts of pressure (head).

Answer. B. Reciprocating pumps.

It gives high heads.
Ex. Hand operated the reciprocating pump.

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

According to me, it is axialflow. So I agree with the given answer.

Axial flow is correct here it is asked for using at supply mains.
