Question

Can you solve this question with the steps? Thank you.

6. To combat global warming, a conceptual thermodynamic cycle design is considered which uses CO, as working fluid. Consider 0.5 kg of CO2 is utilized in a piston-cylinder assembly for this cycle in which piston is massless and friction can be neglected. The cycle consists of three processes as follows. Process 1-92: CO, initially at 27°C and 100 kPa, is compressed isothermally to a pressure of 200 kPa. Process 2-3: CO2 is cooled at constant volume until it returns to its initial pressure of 100 kPa. Process 3>1: CO2 is heated at constant pressure to bring back to its initial state. a. Can CO: at its initial state be assumed as ideal gas? Justify your statement. For the rest of the problem, assume CO; behaves as an ideal gas with variable specific heats. Neglect the effects of changes in kinetic and potential energies. Sketch a P-y diagram for the cycle. Based on the diagram, determine whether this cycle is a power cycle or a refrigeration cycle (clearly specify your reason). b. e. Calculate work for each process, in kJ, and net work for the entire cycle, in kJ.
