Question:

Air in a typical house (Fig. 11.33) is completely exchanged with outside air about every two hours unless care is taken to seal cracks. If the outside air is at 0 8C with 60% humidity and the inside air is maintained at 22 8C, estimate the humidity of the inside air if no humidiï¬er is operating and other moisture inputs are ignored.
