Question

A double acting reciprocating pump has piston diameter 250 mm and piston

rod of diameter 50 mm which is one side only. Length of piston stroke is 350

mm and speed of crank moving the piston is 60 rpm. The suction anddelivery heads are 4.5 m and 18 m respectively. Determine the discharge

capacity of the pump and the power required to operate the pump.​

Explanation:

INTRODUCTION

There are two main types of pumps namely the dynamic and positive displacement pumps.

Dynamic pumps consist of centrifugal, axial and mixed flow pumps. In these cases pressure is

developed by the dynamic action of the impeller on the fluid. Momentum is imparted to the

fluid by dynamic action. This type was discussed in the previous chapter. Positive displacement

pumps consist of reciprocating and rotary types. These types of pumps are discussed in this

chapter. In these types a certain volume of fluid is taken in an enclosed volume and then it is
