Part C only A gas-turbine power generator operates on an ideal air-standard Brayton cycle 1 → 2 → 3 → 4 shown in Fig. 1. The gas temperatures at the compressor inlet, compressor exit, and turbine inlet are T1 = 300 K, T2 = 600 K, and T3 = 1200 K, respectively. Solve Part C below using the variable specific heat assumption. Part C - Determine the heat input qin in the process 2 → 3, the work wC used by the compressor, and the work wT produced by the turbine per kg of air.
Components of a heat pump for supplying heated air to a dwelling are shown in the schematic below. At steady state, Refrigerant 134a enters the compressor at 6 °C, 3.2 bar and is compressed adiabatically to 75 °C, 14 bar. From the compressor, the refrigerant passes through the condenser, where it condenses to liquid at 28 °C, 14 bar. The refrigerant then expands through a throttling valve to 3.2 bar. The states of the refrigerant are shown on the accompanying T-s diagram. Return air from the dwelling enters the condenser at 20 °C, 1 bar with a volumetric flow rate of 0.42 m³/s and exits at 50 °C with a negligible change in pressure. Using the ideal gas model for the air and neglecting kinetic and potential energy effects, (a) determine the rates of entropy production, in kW/K, for control volumes enclosing the condenser, compressor, and expansion valve, respectively. (b) Discuss the sources of irreversibility in the components considered in part (a). Indoor return air T5 = 20°C P₁ = 1…
