Saturated steam at 1(atm) and 100°C is continuously generated from liquid water at I(atm) and 25⁰C by thermal contact with hot air in a counterflow heat exchanger. The air flows steadily at I(atm). Determine values for n (steam)/h(air) for two cases.Air enters the exchanger at 500°C. For both cases, assume a minimum approach Δ T for heat exchange of 10°C
