SOLVED: The temperature at the entrance to a turbine is 1800 K, and the fuel/air ratio is 0.0338. For a turbine temperature ratio τt = 0.75, and polytropic efficiency et = 0.9, calculate the turbine pressure ratio πT and adiabatic efficiency ηT, using:a) CPG model with γ = 1.4b) ACP model with γc = 1.4, γτ = 1.3c) VCP model (use the AFProp software to calculate gas properties)

SOLVED:A multistage axial-flow compressor has a mass flow rate of 100  kg / s and a total pressure ratio of 25 . The compressor polytropic efficiency is ec=0.90. The inlet flow condition to the compressor is described by T12=-35^∘ C and p12= 30 kPa. Assuming the flow in the compressor is adiabatic, and constant gas properties throughout the compressor are assumed, i.e., γ=1.4 and cp=1004  J / kg ·K, calculate (a) compressor exit total temperature Tt 3, in K (b) compressor adiabatic efficiency ηc
