Superheated steam at T1( ^oC) and 20.0 bar is blended with saturated steam at T2( ^oC) and 10.0 bar in a ratio of (1.86 kg of steam at 20 bar / 1.0 kg of steam at 10 bar). The product stream is at 250 ^oC and 10.0 bar. The process operates at steady state. a) Assuming the blender operates adiabatically, what are T1 and T2? 

b) If instead heat is being lost from the blender to the surroundings, is your estimate of T1 too high or too low? Explain.
