In Rankine cycle heat rejection is provided to ............


A) at constant pressure process 

B) at constant temperature process 

C) at constant pressure process 

D) at constant entropy process 

Correct answer : option C ( solution discussed below)


Rankine cycle is working cycle of steam or coal power plant.  In Rankine cycle 2 constant pressure process and 2 constant entropy process.

Process 1 - 2
Heat supplied at constant pressure 

Process 2 -3
Isentropic (constant isentropic) expansion process 

Process 3-4
Heat rejection at constant pressure

Process 4 -1
Isentropic (constant isentropic)  compression process
