Note that for this problem, you are expected to estimate the difference in enthalpy values using cp $($value at $300$ K$)$ times the temperature difference.

A particular power generation system operates on the simple ideal Brayton cycle, across a pressure range from $120$ kPa to $1\mathrm{.}4$ MPa. Air enters the compressor at $25$C and enters the turbine at $1400$C$.$ Using the cold air standard assumptions, determine:

$($a$)$ the temperature at the exit of the compressor $$C

$($b$)$ the temperature at the exit of the turbine $$C

$($c$)$ the compressor work kJ$/$kg

$($d$)$ the turbine work kJ$/$kg

$($e$)$ the back work ratio $\%$

$($f$)$ the amount of heat required kJ$/$kg

$($g$)$ the thermal efficiency of the cycle $\%$
