Saturated steam at 1 atm is discharged from a turbine at a rate of 1150 kg/h. Superheated steam at 300°C and 1 atm is needed as a feed to a heat exchanger; to produce it, the turbine discharge stream is mixed with superheated steam available from a second source at 400°C and 1 atm. The mixing unit operates adiabatically. Calculate the amount of superheated steam at 300°C produced and the required volumetric flow rate of the 400°C steam. Specific enthalpies of the two feed streams and the product stream are obtained from the steam tables and are shown below on the flowchart.

Q2) Saturated steam at 1 atm is discharged from a turbine at a rate of 1150 kg/h. Superheated steam at 300°C and 1 atm is needed as a feed to a heat exchanger; to produce it, the turbine discharge stream is mixed with superheated steam available from a second source at 400°C and 1 atm. The mixing unit operates adiabatically. Calculate the amount of superheated steam at 300°C produced and the required volumetric flow rate of the 400°C steam. Specific enthalpies of the two feed streams and the product stream are obtained from the steam tables and are shown below on the flowchart. Turbine discharge 1150 kg H20(v)/h 1 atm, saturated (100°C) H = 2676 kJ/kg MIXER m2 (kg H20(v)/h] 300°C, 1 atm A = 3074 kJ/kg m [kg H,0(v)/h] 400°C, 1 atm A = 3278 kJ/kg D Focus
