Create the P-V, V-T, P-T diagrams. A straight line on the P-V diagram represents the 4-1 process. Calculate the thermal efficiency of the thermodynamic cycle 1-2-3-4-1. Air (ideal gas, m = 1.2 kg, R=287 J/kg K, k =1.4) is the working fluid in the following thermodynamic processes: 3-4: Constant pressure heating. P1=1bar, T1=27°C, P2=12bar, P3=18bar, U4 = 2u3 (u-specific internal energy). Calculate: 1) 2) 1-2: Adiabatic compression (isentropic efficiency 0.87). 2-3: Constant volume heating. 3) 4) W (total). Q (total). AU (total). AH (total). Create the P-V, V-T, P-T diagrams. A straight line on the P-V diagram represents the 4-1 process.
