Question

Describe the working mechanism of a common hand pump.

Answer 1

Answer:

Handpumps operate on the principles of fluid mechanics. Mechanical energy is used to lift the water from some depth below ground to the surface, and the water is moved by taking advantage of pressure differences. The fluid moves from an area of higher pressure to lower pressure when the piston is moved up and down.
