19.19 Saturated air at 41°F dry bulb (5°C) enters a furnace; it leaves the furnace at 110°F dry bulb (43.3°C) and 0.00543 lb,/lb, (0.00543 kg/kg) and circulates through a factory. Air leaves the factory at 65°F dry bulb (18.3°C) and 63°F wet bulb (17.2°C). a. What is the sensible and latent heat change for the air passing through the factory? b. State whether the air gains or loses sensible and latent heat during each process. [Ans: q, = +6 Btu/lb (14.0 kJ/kg), q1 = +7 Btu/lb (16.3 kJ/kg)]
