1.13 Figure P1.13 depicts the various ways in which an aver- age person gains and loses water in one day. One liter is ingested as food, and the body metabolically produces 0.3 liters. In breath- ing air, the exchange is 0.05 liters while inhaling, and 0.4 liters while exhaling over a one-day period. The body will also lose 0.3, 1.4, 0.2, and 0.35 liters through sweat, urine, feces, and the skin, respectively. To maintain steady state, how much water must be drunk per day?
