The working gas of a thermodynamic cycle is a diatomic gas (assume constant specific heats.) The gas originally starts at 100kPa, 4m ³ and 27° C. It undergoes a four-step process --- • Process A-B: The gas is compressed at constant temperature to one-quarter of its original 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 state a) Make a table of the temperature, pressure, volume, internal energy, enthalpy, entropy and quality factor (T, P, V, U, H & S) 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 (AU, Q, W, AH & AS) during each leg of the cycle. c) Draw well-labelled P-V & T-S diagrams (indicating lines of constant temperature, heat flow, work, etc.) d) Calculate the thermal efficiency of the cycle.
Round eveything to 4 decimal places. Saturated steam at 150°C is used as a working fluid for a device that supplies heat to a reservoir with a temperature of 250°C. Since the device is not 100% efficient, waste heat is produced to a sink of cooling water at 10°C. To be able to maintain the temperature in the reservoir, 2500 kJ of heat should be supplied, is this possible? Prove using entropy. Assume that the working fluid leaves as liquid water at 15°C.
