If a person breathes 10 liters per minute of air at 68 degrees Fand50% relative humidity, how much water per day must theinternalmembranes supply to saturate the air at 98.6 degrees F?(Assume allthe moisture is exhaled) If each gram of water extracts580calories as it is vaporized, how much daily heat lossinkilocalories(food calories) does this represent? (Saturationvaporpressure at 20 degrees C is 17.3 g/m3 and at 37degreesC is 44.0 g/m cubed.
Hint: 1/2 humidity, 1/2 saturation: inhale 17.3/2=8.65saturation
