IntroductionThis chapter begins with a problem to find the pump outlet temperature when given the pump efficiency or vice versaThe pump operation is used to increased the pressure of an inlet liquid stream. Depending on the information specified, the pump calculates either an unknown pressure, temperature or pump efficiency

TYPES OF PUMPSPumps can be classified into two general types : Centrifugal pumps Positive dispacement pumps

Centifugal PumpsCentrifugal pumps basically consist of a stationary pump casing and an impeller mounted on a rotating shaft.

Learning OutcomesOperate in a pump operation in HYSYS to model the pumping processConnect streams to unit operationsDetermine the pump efficiency and outlet temperature

PrerequisitesStart HYSYSSelect componentsDefine and select a fluid packagesAdd and specify material streams

Problem 1Water at 120oC and 3 Bar is fed to a pump that only 10% efficiency. The flowrate of the water is 100 kgmole/h and its outlet pressure from the pump is 5 Bar. Using the Peng-Robinson equations os state as a fluid packages, determine the outlet temperature of the water??

DiscussionThe example shows that pumping liquid can increase their temperature. Pump efficiencytemperatureThis arises because in a low efficient pump, more energy is needed to pump the liquid to get the same outlet pressure of a more efficient pump. So the extra energy gets transferred to fluid

Further Study ( Problem 2)If the outlet temperature is 200oC, what is the efficiency of the pump??
