I need help coding this in EES, I have tried to code it several times and I keep running into errors because I have two more variables than equations. Please only answer this if you can use EES to code it. Thanks

A steam power cycle that incorporates two reheat legs is shown in the sketch below. Steam from the boiler enters the first turbine stage at 1600 psia and 1100F. The steam leaves the first turbine stage at PPI and then enters the reheat section of the boiler where it is reheated back to 950 *F with no pressure drop. The steam then enters the second turbine stage, and leaves at PI4] to a second reheat where it increases temperature to 800 "F. It enters the third turbine stage where it expands to 9 psia. The working fluid is a saturated liquid at 9 psia when it leaves the condenser. Each stage of the turbine has an isentropic efficiency of 80% and the pump has an isentropic efficiency of 85%. The net power output of the cycle is 175,000 hp. Reheat section Steam generator Condense Pump 1) You will build a parametric table in EESlthat explores ranges for both RI2] and PI4] as a means to maximize plant efficiency. Initially, explore RI2] from 600 psi to 200 paia in increments of 100 psia (5 values), and at each value of P[2], explore P[4] from 250 psi to 50 psia in increments of 50 psia (5 values). From this analysis, what RI2] and P[4] should be used for optimal efficiency? Remember, Q.dotin. includes more than just state and 1 A steam power cycle that incorporates two reheat legs is shown in the sketch below.
