please provide all steps clearly

A turbine discharges 200kg/h of saturated steam at 10 bar absolute. It is desired to generate steam at 250C and 10 bar by mixing the turbine discharge with a second stream of superheated steam of 300C and 10 bar. a. If 300kg/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
