A gas power cycle compresses air at 1 bar and 300 K (state 1) through an adiabatic, reversible compressor to 6 bar (state 2). Heat is added to air in a constant pressure heat exchanger such that air leaves the heat exchanger at 6 bar and 1400 K (state 3). Air then expands through an adiabatic, reversible turbine to 1 bar. Heat is rejected from air in another constant pressure heat exchanger to complete the cycle. Mass flow rate of air through all devices is 80 kg/s.
(b) Determine the net power (kW) produced by the power plant.
(c) What is the heat transfer (kW) into the power plant?
(d) Calculate thermal efficiency (%) of the power plant.
(e) Show the cycle on T-s diagram, indicating temperature values and lines of constant pressure.
