A simple ideal Brayton cycle is modified to incor- porate multistage compression with intercooling, multistage expansion with reheating, and regeneration without chang- ing the pressure limits of the cycle. As a result of these modifications,
(a) Does the net work output 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?
(d) Does the heat rejected increase, decrease, or remain the same?

    13. Consider an air-standard Brayton cycle having 3 stages of compression with intercooling, a regenerator, and 3 stages of expansion with reheat. Draw a T-s diagram assuming isentropic compression and expansion, perfect regeneration, inlet temperatures to the 3 compressors equal to the low temperature sink, and inlet temperatures to the 3 turbines equal to the high temperature source. Now consider the limit of infinite stages of compression with intercooling, perfect regeneration, and infinite stages of expansion with reheat. Draw a...
