The air is taken through the following cycle of processes; 1. From an initial temperature of 25°C and pressure of 1 bar it is compressed isothermally to 1/12th of its initial volume. 2. The air temperature is increased to 1200°C by heat transfer at constant pressure 3. The cylinder is cooled by a constant volume heat transfer process until the temperature in the cylinder is 500°C. Calculate; a) The pressure at the end of the compression process (1187 kPa) b) The volume occupied by the gas after the isobaric heat transfer (0.178m3) c) The pressure after the cooling process (623kPa). d) The net work done during the cycle.
