b.	Assuming a 20 MW simple cycle gas turbine with a firing temperature of 1600K develop an analysis of a combined cycle.  Assume that Tmax in the Rankine cycle is 560 C, Pmax = 60 Bar, and Pmin = 0.08 Bar.  Assume an air inlet temperature of 300 K and use realistic component efficiencies.  (nt = 0.88, nc = 0.86, and ?nst = 0.89).  You may use interactive thermodynamics on this assignment but do a hand calculation on the waste heat recovery steam generator.  You may use an open feedwater heater if you want but not a reheat.  Determine the overall cycle efficiency.
