A turbine discharges 216.3 kg/h 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. For 393.2 kg/h of the product stream to be generated , how much heat must be added to the mixer in kW? Report positive umber.

Steam enters the first-stage turbine shown in Fig. P4.50 at 40 bar and 500℃
Steam enters the first-stage turbine shown in Fig. P4.50 at 40 bar and 500℃ with a volumetric flow rate of 90 m3/min. Steam exits the turbine at 20 bar and 400℃. The steam is then reheated at constant pressure to 500℃ before entering the second-stage turbine. Steam leaves the second stage as saturated vapor at 0.6 bar. For operation at steady state, and ignoring stray heat transfer and kinetic and potential energy effects, determine the(a) mass flow rate of the...
