One kg of fluid expands reversibly according to a linear law from 4.2 bar to 1.4 bar. The initial and final volume are 0.004 and 0.02 m² respectively. The fluid then cooled reversibly at constant pressure, and finally compressed reversibly according to a law PV=C back to initial condition of 4.2 bar and 0.004 m³. Calculate the work done for each process, the net work done and sketch the cycle on the P-V diagram. (4480, -1120, -1845 &1515 N-m)

A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat. 4) Create a schematic p-v diagram of the process The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration.
