Using EES WHAT IS THE CODE FOR Design Problem$$ to determine the most efficient power plant that produces $500$ MW Design a steam power plant that works as a Regenerative Rankine cycle with $1$ open feedwater heater by selecting the extraction pressure to optimize cycle efficiency. The available steam conditions at the inlet of the turbine are $10$ MPa and $500$C and the condenser pressure is $10$ kPa. The isentropic efficiency of the turbine is $0\mathrm{.}89$ while it is $0\mathrm{.}8$ for the pump. assume no pressure drop in the heat exchangers. A T$-$s diagram for the cycle should be provided along with a table showing the pressure, temperature, enthalpy, entropy and quality $($where applicable$)$ of all the states at the optimized point. Mention the required flow rate of the working fluid, rate of heat input, rate of heat rejected as well as cycle efficiency at the design point
