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.
Diesel cycle releases 1750 J/mol ofheat. The pressure and temperature at the begin-ning of the compression step are 1 bar and 50°C,and the pressure at the beginning of the expansionis 5 bar.
