Question:-
Assertion (A): The thermal efficiency of Brayton cycle would not necessarily increase with reheat.
Reason (R): Constant pressure lines on the T-s diagram slightly diverge with increase in entropy.
Option (A)
Both A and R are true and R is the correct explanation of A
Option (B)
Both A and R are true but R is NOT the correct explanation of A
Option(C)
A is true but R is false
Option(D)
A is false but R is true
Correct Option:
(B)
Question Solution:
It depends upon the pressure ratio at which reheating is taking place. The extra work produced due to expansion in second stage will also required heat addition.
