HW ll]I Propane contained inside a closed piston-cylinder device undergoes four processes. Process 1 to 2: A constant temperature process from an absolute pressure of 4 bar and a temperature of 0C (State 1) to saturated vapor [State 2) Process 2 to 3: A constant pressure process to saturated liquid-vapor mixture of quality 0.3 (State 3) Process 3 to 4: A constant volume process to an absolute pressure of 10 bar (State 4) Process 4 to 5: A constant pressure process to a temperature of 0C [State 5} (a) Considering the constant temperature process from State 1 to State 2 to be polytropic Pv" = constant, nd the value ofn. (b) Calculate the specic work for each process, in kakg. (c) Determine the specic heat transfer for each process, in 1(ng. ((31) Show the four processes on P-v diagram relative to the vapor dome and the appropriate lines of constant temperature for the five states. Label states and identify process directions with arrows. For propane: Pmrim = 42.5 bar and Tcritical = 96.6C
