A turbine discharges 200 kg/h of saturated steam at 10.0 bar. It is desired to generate steam at 250°C and 10.0 bar by mixing the turbine discharge with a second stream of superheated steam of 300°C and 10.0 bar.

Problem 4
A turbine discharges 200 kg/h of saturated steam at 10.0 bar. It is desired to generate steam at
250°C and 10.0 bar by mixing the turbine discharge with a second stream of superheated steam
of 300°C and 10.0 bar.
a) If 300 kg/hr of the product steam is to be generated, how much heat must be added to the
mixer?
b) If now the process is done adiabatically (no heat loss or gain), at what rate must the
product steam be generated?
