Here, natural gas powers a Brayton cycle turbine, and the exhaustfrom that turbine is then fed into a steam generator to run a Rankine cycleturbine.a) The high temperature in the Brayton cycle turbine is 1500K. The exhaust for the Braytoncycle exits at about 850K. What is the maximum efficiency that you could expect from aheat engine operating between these two temperature extremes? b) A heat exchanger is able to deliver the Brayton cycle exhaust to a Rankine (steam) cycle.The the final outgoing temperature from this steam cycle is 325K.
