Question

Which of the following pumps is preferred for flood control and irrigation applications?
(A) Centrifugal pump
(B) Axial Flow pump
(C) Mixed flow pump
(D) Reciprocating pump

Answer 1

Hint :A pump is a device which moves fluids or some other slurries by mechanical action which is typically converted from electrical energy into Hydraulic energy. Pumps are classified into different groups which is based on the method used by the pump to move the fluid. Here we will understand all the given terms.

Complete Step By Step Answer:
Centrifugal pump is the pump which can be used for handling the huge amount of liquids which extremely provides the high flow rates.
The axial pump can be defined as the pump in which fluid flows axially to the rotation of the propeller.
In Axial flow, the fluid flows parallel to the axis of the rotation as with the turbine.
Axial flow pump contains a propeller or the centrifugal impeller in the casing which is preferred for flood control and other irrigation applications.
From the given multiple choices, the option B is the correct answer.

Note :
Know the difference and applications of different types of pumps. Mixed flow pump is the centrifugal pump with the mixed flow impeller with the high specific speeds which are usually designed with an axial tubular casing. A reciprocating pump is the positive displacement pump which utilizes the plunger or the piston to change a cavity’s volume and produces the pressure differential which are used for low-flow, high pressure operations.
