It works on the principle of forced vertex flow and
mechanical energy is converted into hydraulic energy ie
pressure energy.Mainly the centrifugal pump has two
components ,Impeller & shaft.when the impeller is moved in
the liquid,there is centrifugal force is applied on rotating
fluid.so we can define it as the pump lifts the fluid with
aid of atmospheric pressure and pressurizes it and dicharges
from casing with high velocity.

In Rankine Cycle we use the concept of Tm(mean temperature of heat addition).In actual cycle the efficiency comes as n=1-T2/T1 Taking Tm into consideration it comes as n=1-T2/Tm as T1>Tm so the efficiency for both case will not same for a same cycle. Can anybody explain how it is possible? Advance appreciation for your effort.Thanks
