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.
