A turbine discharges 200 kg/h of saturated steam at 10 bar absolute. It is desired to generate steam at 250 °C and 10 bar by mixing the turbine discharge with a second stream of supersaturated steam of 300 °C and 10 bar. (a) Sketch a diagram to express the process. (b) If 300 kg/h of the product steam is to be generated, how much heat must be added to the mixer? (c) If instead the mixing is carried out adiabatically, at what rate is the product steam generated?

i need help with all parts in this question asap 

A turbine discharges 200 kg/h of saturated steam at 10 bar absolute. It is desired to generate
steam at 250 °C and 10 bar by mixing the turbine discharge with a second stream of
supersaturated steam of 300 °C and 10 bar.
(a) Sketch a diagram to express the process.
(b) If 300 kg/h of the product steam is to be generated, how much heat must be added to the
mixer?
(c) If instead the mixing is carried out adiabatically, at what rate is the product steam
generated?
