At T=293K and at 50% relative humidity, the pressure of water vapor in equilibrium with liquid water is 0.0115atm. Using the information in P1.8, determine what mass of water is inhaled per hour and the net loss of water through respiration per hour. (P1.8 - In normal respiration, adult exhales about 500 L of air per hour. The exhaled air is saturated with water vapor at body temperature T=310 K. At this temperature water vapor in quilibrium with liquid water has pressure of P=0.062 atm.)
