Thermodynamics, please show all work. Step 1 and 2.
Hot combustion gases, modeled as air behaving as an ideal gas, enter a turbine at 145 lbf/in.2, 2700°R with a mass flow rate of 0.32 lb/s and exit at 29 lbf/in.2 and 1620°R. If heat transfer from the turbine to its surroundings occurs at a rate of 20.36 Btu/s, determine the power output of the turbine, in hp. W cv = i hp

Air enters a diffuser operating at steady state at 540°R, 15 Ilbf/in.?, with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. The ratio of the exit area to the inlet area is 6. Assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °R, and pressure, in Ibf/in.?, at the exit.
Air in a closed piston-cylinder arrangement is expanded from the initial pressure of 9 bar and initial volume of 0.023 m to the final state of p = 3 bar. A polytropic relation of pV^1.27 = constant was followed between pressure and volume for the process. The specific internal energy at the initial and final states are 160 and 97 kJ/kg, respectively. The mass of the air is 0.3 kg. Neglecting the effect of kinetic and potential energy, determine the heat transfer, in kJ.
Air expands through a turbine operating at steady state. At the inlet, p₁ = 150 lbf/in.², T₁ = 1400°R, and at the exit, p2 = 14.8 lbf/in.², T2 = 800°R. The mass flow rate of air entering the turbine is 17 lb/s, and 65,000 Btu/h of energy is rejected by heat transfer. Neglecting kinetic and potential energy effects, determine the power developed, in hp. Wev = i 6396.24 hp

Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate of 39 m³/min and exits at 12 bar, 400 K. Heat transfer occurs at a rate of 6.5 kW from the compressor to its surroundings.
