2 kg/h of superheated steam at 10 bar is combined with 1 kg/h of saturated steam at 5 bar. The product stream is at 250oC and 5 bar. Assuming steady-state operation with no heat loss to the surroundings, determine the temperatures of the inlet streams. If in fact heat is being lost to the surroundings, is your estimate of temperature for the superheated steam too high or too low? Explain.
