An adiabatic air compressor is to be

powered by a direct$-$coupled adiabatic steam

turbine that is also driving a generator. Steam

enters the turbine at $12\mathrm{.}5$MPa and $500C$ at

a rate of $25k\frac{g}{s}$ and exits at $10$kPa and a

quality of $0\mathrm{.}92.$ Air enters the compressor at

$98$kPa and $295K$ at a rate of $10k\frac{g}{s}$ and

exits at $1$MPa and $620K.$ Determine the net

power delivered to the generator by the

turbine.
