7.43. Superheated steam at T(C) and 10.0 bar is combined with saturated steam at T(C) and 7.0 bar in a ratio (1.96 kg of steam at 10 bar)/(1.0 kg of steam at 7 bar). The product stream is at 250C and 7.0 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 7, too high or too low? Briefly explain.
