- Q1. How pumps work?
- Ans.
Pumps are devices that use mechanical action to move fluids from one place to another.
Pumps work by creating a pressure difference to push fluids through a system.
They typically consist of an inlet, an outlet, and an impeller or rotor.
The impeller rotates, creating centrifugal force that pushes the fluid outwards.
Positive displacement pumps use reciprocating or rotary motion to move fluid in discrete volumes.
