The working gas of a thermodynamic cycle is air(assume constant specific heats.)The gas originally starts at 100kPa, 4m3and 27oC. It undergoes a four step process:Process A-B: The gas is compressed at constant temperature to one-fourth of its volume. Process B-C: The volume of the gas is then doubled at constant pressure. Process C-D:The gas then undergoes an adiabatic expansion.Process D-A:The gas then undergoes a constant volume process back to its original statea) Make a table of the temperature, pressure, volume, internal energy, enthalpy, entropy and quality factor (T, P, V, U, H, S & x) at the start of each process.b) Make a table of the change in internal energy, heat flow, work done, change in enthalpy, and change in entropy (U, Q, W, H, S) during each leg of the cycle.c) Draw a well-labelled P-v diagram (indicating lines of constant temperature.)d) Calculate the thermal efficiency of the cycle.
