B) at constant pressure process
C) at constant temperature process
D) at constant entropy process
Correct answer : option B ( solution discussed below)
Solution
Rankine cycle is working cycle of steam power plant. In Rankine cycle two constant pressure process and two constant entropy process.
Process 1 - 2
Heat addition at constant pressure
Process 2 -3
Isentropic expansion process
Process 3-4
Heat rejection at constant pressure
Process 4 -1
Isentropic compression process
