Saturated steam at 1 atm and 100°C is continuously generated from liquid water at 1 atm and 25°C by thermal contact with hot air in a counterflow heat exchanger. The air flows steadily at 1 atm. Determine values for m.m. (steam)/ n.n. (air) for the following cases.
Consider that air enters the exchanger at 1000°C and exits at 35°C.
The value for ?? m. (steam)/?? n. (air) is
