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 the figure below.
Determine:
(a) the mass flow rate of air, in kg/s.
(b) the total rate of heat transfer, in kW, to the working fluid passing through the Combustor 1 and Combustor 2.
(c) the percent thermal efficiency.
