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

Nowadays‚ a Pitot tube would be of use as a speedometer on aeroplanes. It is also found useful in industries where velocity measurements are required‚ where an anemometer may not be the most efficient instrument to use. There are three types of pitot tubes: Pitot tubes‚ Static tubes‚ and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°‚ with an open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant

artificial nutrition and hydration as a form of life support is one decision that some people have to make.

A tube feeding is a medical procedure that people can accept or deny. Feeding tubes provide a chemically balanced mix of nutrients and fluid to those who are unable to swallow‚ eat‚ or drink enough nutrition
