QUESTION 9 The following processes occurs in a reversible thermodynamic cycle: 1-2: Reversible polytropic compression at pressure 0.8 bar at volume 0.08 m3 to a pressure 10.1 bar and specific volume 0.3 m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 2.3 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 kllo or mega.
