The T–S diagram of two cycles for the operation of an engine are shown in figure below.


The numerical values of the parameters T1 , T2 , S1 and S2 in the two figures are the same, then which cycle has greater efficiency?
Select one:
  • a)
    First
  • b)
    Second
  • c)
    Both have equal efficience
  • d)
    None of the above
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The T–S diagram of two cycles for the operation of an engine are...
Efficiency  

For curve


Available energy per cycle is
Q1 – Q2 = Area of curve (ABC)
Q1 = Total area of curve (ABED)
⇒ Area of curve is same for both figures, but total area is more for Fig. 1.

Hence, second figure has greater efficiency.
The correct answer is: Second
