i need help with #6

ratio P/P. Question 6 (10 points): Consider the Brayton cycle for a spacecraft as sketched in Figure 2: - T-HO 2-10 P-180 P ++ ON -ON 35 NOR luw The working fluid is Argon, well modelled as a CPIG. For Argon we have R=0.208 kJ/kgK, cp=0.52 kJ/kgK. Take into account the efficiency of the compressor and turbine and find the (0) The net work (3p) The thermal efficiency (3p) (iii) Plot the cycle on the Ts diagram (2p) (iv) The Carnot efficiency between the same T bounds (2p)
