-
AEqual to
-
BHigher than by a fixed margin
-
CLower than by a fixed margin

DUnrelated to
Answer
Correct Answer: Equal to
Explanation
Concept/ApproachPerfect (complete) intercooling brings the air temperature between stages back to the initial inlet (atmospheric) temperature, minimizing total compression work for given pressure ratio.
ResultTafter intercooler = Tatmospheric inlet.
Final AnswerEqual to.
