Q2. How does a centrifugal pump work?
Ans. 
A centrifugal pump works by converting mechanical energy from a motor into kinetic energy in a fluid through the rotation of an impeller.
• Centrifugal pump uses an impeller to rotate and create a centrifugal force to push the fluid outward.

• The fluid enters the pump through the center of the impeller and is accelerated by the rotating blades.

• The kinetic energy of the fluid increases as it moves radially outward, creating ...read more

Q3. What is viscosity?
Ans. 
Viscosity is a measure of a fluid's resistance to flow.
• Viscosity is the internal friction of a moving fluid.

• It is the property that determines how easily a fluid can flow.

• Higher viscosity fluids flow more slowly than lower viscosity fluids.

• Examples of high viscosity fluids include honey and molasses, while water has low viscosity.
