In a steady-state operating power plant, saturated liquid H2O at 122 deg C is fed to a boiler at 3.756 m/s through a pipe (0.03 m diameter). It leaves the boiler at 9 bar and 88.7 m/s. Then, it enters the turbine through a constant 0.13 m diameter pipe. The exit pipe of the turbine is 0.3 m in diameter and T = 310ºC while P = 1.37 bar. If 2.5 kg/s water is fed and there is change in KE, prove that the fluid enters the turbine at 637.06 deg C.

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.
