A steam power plant operates on a Rankine cycle and has an open feedwater heater. Heat is rejected in the condenser at 30kPa, while the boiler has a pressure of 8MPA. Some of the steam is extracted mi- expansion at 0.4MPA to heat the open feedwater heater. The turbine inlet temperature is 480°C. First draw the T-s diagram for this cycle. Use the number convention from the device diagram below and label all work and heat flows. Then, determine the net work per kilogram of steam and the cycle's thermal efficiency.

Required information. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.

Consider a steam power plant, which can be modeled using the ideal reheat Rankine cycle. The steam entering the high- pressure turbine is at 6 MPa and 400 degrees C and leaves at 2 MPa. The steam is then reheated to 400 C at constant pressure, before it expands to 20 kPa in the low-pressure turbine.
