A turbine discharges 250 kg/h of saturated steam at 20 bar. The turbine discharge is mixed with a second stream of superheated steam at 350°C and 20 bar to produce steam at 300°C and 20 bar. a. If 400 kg/h of the product steam is to be generated, how much heat must be added to the mixer? b. If instead the mixing is carried out adiabatically, at what rate is the product steam generated?
