Solve with numerical values from steam table step by step. A Brayton Cycle operates with two stage compression with intercooling back

to $T_1.$ The pressure ratio across each stage $4.$ Air enters the cycle at a

pressure of $14$ psia and temperature of $100F.$ The maximum temperature of

the cycle is $1690F.$ The isentropic efficiencies of the compressors and turbine

are $0\mathrm{.}90.$ Assume temperature dependent properties $($Table A$-22$ E$).$

a$.$ Draw the T$-$s diagram

b$.$ Determine the back work ratio

c$.$ Determine the thermal efficiency of the cycle
