Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

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.
