Question
An automobile industry using piston cylinder arrangement for their operation it under goes a thermodynamic cycle which includes three processes with an initial state where pressure is 1.5 bar, volume is 2 m3 and internal energy equals to 480 kJ. The processes are as follows: 1)first stage to second stage: Compression with pV equals to constant to p2 is equals to 2 bar, U2 equals to 720 kJ 2)Second stage to third stage: work is equals to zero, and Q2-3 = - 150 kJ 3)Stage third to one: work is equals to 75 kJ. Neglecting kinetic energy and potential energy changes, find the heat transfer Q1-2 and Q3-1.
