A steam turbine is used to produce work. Into the

turbine flows stream A at $895$ kg$/$hr steam at $530$C and $4\mathrm{.}50$ MPa.

Out of the turbine flows two streams $$ stream B at $225$ kg$/$hr$,1\mathrm{.}80$

MPa and $310$C$,$ and stream C which is a mixture of vapor and

liquid at $0\mathrm{.}87$ MPa. A portion of stream C is bled through a throttle

to $0\mathrm{.}25$ MPa and found to be at $159$C $($stream D$).$

a$)$ How much work can be produced in kW if the turbine is

operating adiabatically?

b$)$ You are actually achieving $110$ kW out of the turbine. How

much heat was lost in the turbine?

c$)$ What is the quality of stream C$?$

d$)$ What is the temperature of stream C$?$Problem $1$: A steam turbine is used to produce work. Into the
