Design a steam power plant of 1 MW using a rankine cycle. Describe the rankine cycle with additional modifications e.g reheat, regeneration (feedwater) to improve efficient and it's T-S diagram. In your analysis, write down state equations and consider the losses associated with each component to calculate overall thermal efficiency. Also perform a cost analysis for all the equipment for a period of 10 years.

(2) Non-ideal Rankine Recognizing that the Rankine cycle described in question (1) cannot be ideal in reality, your supervisor asks you to perform a more accurate Thermodynamic analysis. She tells you that the States 1, 3 and the mass flowrate are identical to those given above. Additionally, the pump manufacturer specifies its isentropic efficiency, np = 0.8. Through experimental measurement techniques (and the mathematical relations in Chapter 12), the specific entropy of water at State 4 is found to be...
Steam power plant using the reheat Rankine cycle
A steam power plant operates using the reheat Rankine cycle. Steam enters the high pressure turbine at 12.5 MPa and 550ºC at a rate of 7.7 kg/s and leaves at 2MPa. Steam is then reheated at a constant pressure to 450ºC before it expands in the low pressure turbine. The isentropic efficiencies of the turbine and the pumpare 85% and 90%, respectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit...
