- 4. thermodynamicsarrow_forwardThe following processes occurs in a reversible thermodynamic cycle: 1-2: Reversible polytropic compression at pressure 0.5 bar at volume 0.08 m3 to a pressure 10.1 bar and specific volume 0.5 m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 3 bar. 3-1: Reversible cooling at constant volume to the initial state. Calculate the work for the compression in the process to 2 decimal places. Not in kilo or megaarrow_forward1. A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: Process 1-2: Compression with PV = constant, from P₁ = 1 bar, V₁ = 2 m³ to V₂ = 0.2 m³, U₂ − U₁ = 100 kJ; 2 Process 2-3: Constant volume to P3 = P₁; Process 3-1: Constant-pressure and adiabatic process. Neglect the changes of kinetic and potential energy in all three processes. (a) Sketch the cycle on a P-V diagram; (b) Determine the net work (i.e., W12 + W23 + W31) of the cycle, in kJ; (c) Determine the heat transfer for process 2-3, in kJ. Hint: System's state variables remain unchanged after a cycle, i.e. (U₂ − U₁) + (U3 − U₂) + (U₁ − U3) = 0arrow_forward
