L&T Energy Hydrocarbon Mechanical Engineer Interview Questions and Answers

The rpm and discharge of a pump are key parameters that determine its performance.

• RPM (revolutions per minute) is the rotational speed of the pump's shaft.

• Discharge refers to the volume of fluid that the pump can move in a given time.

• The rpm and discharge of a pump are typically provided by the manufacturer in the pump's specifications.

• For example, a centrifugal pump may have an rpm of 1750 and a discharge of 500 gallo
