The boiler pressure is l1000 psia, the extraction pressure is 200 psia, and the condenser pressure is 1 psia. The high-pressure turbine inlet temperature is 1000 F. The water leaving the con- denser is saturated liquid. The exit state of the feedwater heater is also saturated liquid.

Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.
