ABSTRACT

Fluid interpenetration generally occurs when positive displacement takes place in a liquid motive force. It is most commonly caused by the acceleration and deceleration of the fluid. This uncontrolled energy appears as pressure spikes. Vibration and interpenetration between the water flows and mixture components is the visible example of pulsation and is the culprit that usually leads the way to component failure. A pump’s motor exerts a torque on a shaft that delivers energy to the pump’s impeller, forcing it

points. When the pump starts, pressure can increase rapidly. Whenever power sags or fails, the pump slows or stops and a sudden drop in pressure propagates downstream. The similarity of the transient conditions caused by different source devices provides the key to transient analysis in a wide range of different systems: understand the initial state of the system and the ways in which energy and mass are added or removed from it. This is best illustrated by an example for typical binary mixtures [1-5].
