You are required to design a steam turbine plant with the following specifications: the thermal efficiency should be at least 45%, one High-Pressure Turbine (HPT), one Intermediate-Pressure Turbine (IPT), one Low-Pressure Turbine (LPT), two interstage reheaters (the number can be increased, not used, or a closed feedwater heater option can be chosen), two-stage closed feedwater heaters (the number can be increased), and one deaerator. The turbines in the plant are assumed to have an isentropic efficiency of 85%, while all pumps are assumed to have an isentropic efficiency of 60%.

REQUIREMENTS:

1)The system and its T-s diagram should be drawn on an A3-sized (420x297 mm) paper, and the state points should be marked on it (20 points).
2)A table in the format below should be prepared on an A4-sized (297x210 mm) paper, including the mass flow rate (m, kg/s), pressure (P, kPa), temperature (T, °C), enthalpy (h, kJ/kg), and entropy (s, kJ/kgK) values for all flow points in the plant (30 points).
3)All calculations should be done using the EES program, and the coding associated with the calculations should be included in the assignment (20 points).
4. Energy equations used in the thermodynamic calculations of the system components should be prepared according to the following template (for each system component). The net power of the plant (kW) and thermal efficiency should be written in the last row of the table (30 points).
