Manometric Head of a Centrifugal Pump
Definition: The manometric head of a centrifugal pump is the total head developed by the pump. It is a measure of the energy imparted to the fluid by the pump and is expressed in meters of fluid.
Factors Affecting Manometric Head: The manometric head depends on several factors, including:
- Velocity head at the pump outlet.
- Pressure head at the pump outlet.
- Suction head (or lift).
- Frictional losses within the pump (impeller, casing).
However, it is important to understand that the manometric head does not depend on the frictional losses occurring outside the pump, such as in the suction and delivery pipes or bearings.
Correct Option Analysis:
The correct option is:
Option 1: Frictional losses in bearings.
This option is correct because the manometric head of a centrifugal pump is independent of the frictional losses in bearings. The manometric head is concerned with the energy imparted to the fluid by the pump, which is not affected by external frictional losses in bearings. These losses do not alter the head developed by the pump
