CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping. Centrifugal pumps are used for

Physics in Roller Coasters There is a lot of Physics in a roller coaster. It contains a lot of potential and kinetic energy‚ and also centripetal force. All of these factors will define how the roller coaster really works. As we all know‚ or some of us know‚ roller coasters doesn’t use engine to operate the ride. It depends on converting potential energy into kinetic energy. Cars will need a certain amount of pull or push to reach a certain peek of the track. Upon reaching the peak‚ the energy

distinction in terms of the centripetal force and centrifugal force with Russia. Dagestan represents the where Chechnya represents the latter. The conflict of Chechnya traces back to World War 2 where the entire Chechen population was deported to Siberia and northern part of Kazakhstan by the Soviet Union government. The movement rose up Chechnya’s distaste towards the Soviet rule and rebellion took place in hope of seeking independence from USSR. Another centripetal force is religion. Unlike most

force is the centripetal (“center-seeking”) force. For a planet orbiting the sun‚ the force is gravitational; for an object twirled on a string‚ the force is mechanical; for an electron orbiting an atom‚ it is electrical. The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion‚ for every action there is an equal and opposite reaction. The centripetal force‚ the

We will use a stopper moving in a circle to create an upward force on the hanging mass; at equilibrium‚ the upward force on the mass will exactly equal the centripetal force.
