Engineering Thermodynamics Question about a generator and turbine as a system

[rjrod5]

Hey guys, sAn industrial process discharges 200,000 cubic ft/min of gaseous combustion products at 400 F and 1 atm. As shown in the figure, a proposed system for utilizing the combustion products combines a heat-recovery steam generator with a turbine. At steady state, heat transfer from the outer surfaces of the steam generator and turbine can be ignored, as can the changes in kinetic and potential energies of the flowing streams. There is no significant pressure drop for the water flowing through the steam generator. The combustion products can be modeled as air as an ideal gas. a) Determine the turbine inlet temperature, in F. b) Determine the power developed by the turbine, in Btu/min
