Question number 3. Thermodynamics.
Show transcribed image text Air contained in a piston cylinder assembly under goes two processes in series from an initial state where P1 = 2.0 bar, T1 = 300 L, & V2 = 0.1 m^3/kg Processes 1-2: constant-pressure until the section volume is 0.3 m^3/kg. Processes 2-3: constant-temperature until the pressure id 0.1 bar Sketch the two processes on a P-V diagram. Assuming ideal gas behavior, determine : The temperature at state 2 in bar The specific volume at state 3 The work and the heat transfer in kJ/kg for each process. The specific heat ratio, k = 1.4
