Problem 80P

Regeneration, Reheat, and Compression with Intercooling An air-standard regenerative Brayton cycle operating at steady state with intercooling and reheat produces 10 MW of power. Operating data at principal states in the cycle are given in the table below. The states are numbered as in Fig. 9.19. Sketch the T-s diagram for the cycle and determine

(a) the mass flow rate of air, in kg/s.

(b) the rate of heat transfer, in kW, to the working fluid passing through each combustor.

(c) the thermal efficiency.
