Solve with numerical values from steam table step by step. An ideal Brayton Cycle with regeneration operates with a pressure ratio of $14.$

Air enters the cycle at a pressure of $100$ kPa and temperature of $40C.$ The

maximum temperature of the cycle is $1500C.$ The regenerator has an

effectiveness of $80\%.$ Assume the cold air standard.

a$.$ Determine the thermal efficiency this cycle.

b$.$ Determine the air mass flow rate for a net power output of $50$ MW $.$

c$.$ If the heating value of the Liquefied Natural Gas fuel is $25M\frac{J}{L}$ and the cost

is $$\frac{0\mathrm{.}18}{L},$ determine the fuel cost per day.
