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

12.5MPa

and

500\\\\deg C

at a rate of

25k(g)/(s)

and exits at

10kPa

and a quality of 0.92 . Air enters the compressor at

98kPa

and

295K

at a rate of

10.5k(g)/(s)

and exits at

1MPa

and

620K

. Determine the net power (

W_(net )

) delivered to the generator by the turbine

(W_(net )^()

)

=

(

W_(turb, out )^()-W_(comp, in )^())

.
