An ideal gas initially at 600K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. In step 12 (the process that changes the system from State 1 to State 2), pressure decreases isothermally to 3bar; in step 23, pressure decreases at constant volume to 2bar; in step 34 volume decreases at constant pressure; and in step 41, the gas returns adiabatically to its initial state. Take Cp=(7/2)R and Cv=(5/2)R. Determine the efficiency of the cycle. (Hint:...

A system consists of 2.320 g of carbon monoxide gas initially at temperature 400.0 K and pressure 0.6250 bar. Assume the heat capacity of carbon monoxide is constant at the value found for 298.15 K in the data tables of the Appendix (see also Figure 2.8). The system undergoes the following cyclic process: Step a) Reversible isothermal expansion to double the initial volume. Step b) Constant volume extraction of heat from the system (to a temperature and pressure consistent with...

Problem 4 Consider a gas power cycle executed in a closed system with 0.08 kg of gas. The gas is initially at 120 kPa, 2°C. First,910 kJ/kg of heat is added under constant volume. Then, more heat is added under constant pressure such that the gas reaches 1387°C. Then, the gas is expanded isentropically to 120 kPa. Finally, heat is rejected from the system under constant pressure such that it returns the gas to its initial state. Assuming air-standard cycle...
