An ideal gas initially at 600 K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. In step 1-2, pressure decreases isothermally to 3 bar; in step 2-3, pressure decreases at constant volume to 2 bar; in step 3-4, volume decreases at constant pressure; and in step 4-1, the gas returns adiabatically to its initial state. Take Cp = (7/2)R and Cv = (5/2)R. (a) Sketch the cycle on a PV diagram. (b) Determine (where unknown) both T and P for states 1, 2, 3, and 4. (c) Calculate Q, W, AU, and AH for each step of the cycle.

Refrigerant 22 enters a compressor operating at steady state and is compressed adiabatically to a higher pressure. Would you expect the power input to the compressor to be greater in an internally reversible compression or an actual compression?
An ideal gas is undergoing a mechanically reversible process consisting of four steps: (1->2) adiabatic compression from Vi=0.1 m3, Pl=1 bar to V2, P2=5 bar (2->3) isobaric expansion at P2=5 bar until a temperature T3=80 'C is reached. (3->4) isothermal expansion until a pressure of P4=3.5 bar is reached. (4->1) isochoric process to return to Pi, V, .

One mole of an ideal gas, initially at 30 [°C] and 1 [bar], is changed to 130 [°C] and 10 [bar] by two different mechanically reversible processes: • The gas is first heated at constant volume until its temperature is 130 [°C], then it is compressed isothermallyuntil its pressure is 10 [bar].• The gas is first compressed adiabatically; then it is heated isobarically to 130 [°C] and 10 [bar]. Calculate Q, W, ΔU, and ΔH in [J] for each case. Take Cp = 5/2R and Cv = 3/2R.

Water is compressed adiabatically, but inefficiently, from p1 = 150 kPa and T1 = 160 ∘C to a pressureof p2 = 700 kPa. A throttle valve is connected to the outlet of the compressor and has a temperature reading atits outlet of T3 = 440 ∘C at atmospheric pressure (1 bar). If the compressor operates at steady state, stray heattransfer can be neglected, and the changes in kinetic and potential energy are negligible, determine the isentropicefficiency of the compressor, in percent.
