The following process occurs in a reversible thermodynamic cycle : 1-2 : Reversible polytropic compression at pressure 0,5 bar at volume 0,07 m³ to a pressure 10,2 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 2,6 bar. 3-1 : Reversible cooling at constant volume to the initial state. Calculate : 1)The mass of fluid present 2) In steps on how to determine the value of the compression index n. 3)The compression work 4)the work done at constant volume 5) Net work
