Saturated steam at 1 atm is discharged from a turbine at a rate of 1150 kg/h. Superheated steam at 300^o 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^o C and 1 atm, such that the product is superheated steam at 300^o C and 1 atm. The mixing unit operates adiabatically. Calculate the amount of superheated steam at 300^o C produced and the required volumetric flow rate of the 400^o C steam.
