MCQ
In Rankine cycle heat rejection is provided to ............
Options
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)
Solution
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
