Design a gas power plant that works as a non-ideal Regenerative Brayton cycle by determining the pressure ratio required to optimize the net power output of the cycle. The minimum cycle temperature is 300 K while the maximum cycle temperature is 1780 K. The isentropic efficiency of the turbine is 85% while that of the compressor is 75%. The effectiveness of the regenerator is to be taken as 0.8 while the gas flow rate is 30 kg/s. A T-s diagram for the cycle should be provided along with a table showing the pressure and temperature of all the states at the optimized point. Also, mention the cycle efficiency as well as the rate of heat addition and rejection at the optimized point taking the working fluid to be (i) air, and (ii) helium. Ignore pressure drops in the heat exchangers and assume constant specific heats at room temperature

note: i need solution with ees program (detailed information)
