A building consists of two zones A and B (see Figure 5.5). Only zone A is heated by a furnace, which generates 80,000 Btu/hr. The heat capacity of zone A is 1/4°F per thousand Btu. The time constant for heat transfer between zone A and the outside is 4 hr, A B 4 hr 2 hr Shr 5 hr Figure 5.5 Two-zone building with one zone heated between the unheated zone B and the outside is 5 hr, and between the two zones is 2 hr. If the outside temperature stays at 0°F, how cold does it eventually get in the unheated zone B?
