A steam turbine operates with steam at inlet conditions of 3.5
MPa and 3500 C. The exit stream leave the turbine is at 0.8 MPa and
is known to contain a mixture of saturated vapor and liquid. The
steam rate through the turbine is 1000 kg/h. A (negligible)
fraction of exit stream is bled through a throttle valve to 0.10
MPa and is found to be 1250 C. The measured output of the turbine
is 100 kW.
