Saturated steam at 1(atm) and 100°C is continuously generated from liquid water at1(atm)
Chapter 4, Problem 4.52(choose chapter or problem)
Saturated steam at 1(atm) and 100°C is continuously generated from liquid water at1(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 ? (steam)/ n ? (air) for two cases:
(a) Air enters the exchanger at 1000°C.
(b) Air enters the exchanger at 500°C.
For both cases, assume a minimum approach ?T for heat exchange of 10°C.
