  Buoyancy: Whenever a bodt is immersed wholly or partially in a fluid it is subjected to an upward force which tends to lift it up. This tendency for a immersed body to be lifted up in the fluid, due to an upward force opposite to action of gravity is known as buoyancy. The force tending to lift up the body under such conditions is known as buoyancy force or force of buoyancy or upthrust. The magnitude of the buoyant force can be determined by Archimedes principle which states as follow ”When a body is immersed in a fluid either wholly or partially, it is buoyed or lifted up by a force, which is equal to the weight of fluid displacement by the body.   Center of Buoyancy: The point of application the force of buoyancy on the body is known as the center of buoyancy. It is always the center of gravity of the volume of fluid displacement.                      Characteristics of a Centrifugal Pump     Merits of Centrifygal Pump
