I need help on this assignment: Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110℃ from water at 30℃ in a boiler. This steam will be distributed to several buildings on a university campus for space heating. A Brayton cycle with a pressure ration of 6 is to be used for this purpose. Plot the following:(a) The mechanical power produced,(b) the flow rate of the produced steam,(c) the maximum cycle temperature, all as functions of the rate at which heat is added to the cycle.
