Superheated steam at T₁(°C) and 20.0 bar is blended with saturated steam at T₂(°C) and 10.0 bar in a ratio (1.96 kg of steam at 20 bar)/(1.0 kg of steam at 10 bar). The product stream is at 250°C and 10.0 bar. The process operates at steady state.

(a) Calculate T₁ and T₂, assuming that the blender operates adiabatically.

(b) If in fact heat is being lost from the blender to the surroundings, is your estimate of T₁ too high or too low? Briefly explain.
