Steam enters a steady-flow turbine with a mass flow rate of 20 kg/s at 600 C (Celsius), 5 MPa, and a negligible velocity. The steam expands in the turbine to a saturated vapor at 500 kPa where 10 percent of the steam is removed for some other use. The remainder of the steam is reheated to 600 C (Celsius in the reheater and then expands to the turbine exit where the pressure is 10 kPa and specific volume is 12.47 m3/kg. If the turbine is adiabatic, determine the ratio of the rate of heat added in the reheater to the rate of work done by the steam during this process.

Question
Transcribed Image Text:Steam enters a steady-flow turbine
with a mass flow rate of 20 kg/s at 600
C (Celsius), 5 MPa, and a negligible
velocity. The steam expands in the
turbine to a saturated vapor at 500 kPa
where 10 percent of the steam is
removed for some other use. The
remainder of the steam is reheated to
600 C (Celsius in the reheater and then
expands to the turbine exit where the
pressure is 10 kPa and specific volume
is 12.47 m3/kg. If the turbine is
adiabatic, determine the ratio of the
rate of heat added in the reheater to
the rate of work done by the steam
during this process.
