Discuss the below in detail:
Q: The single-stage compression process of an ideal Brayton cycle without regeneration is replaced by a multistage compression process with intercooling between the same pressure limits. As a result of this modification,
(a) Does the compressor work increase, decrease, or remain the same?
(b) Does the back work ratio increase, decrease, or remain the same?
(c) Does the thermal efficiency increase, decrease, or remain the same?
