One size for adults resting medium converts the chemical energy in food into energy internal rates of 120 W, called her basal metabolic rate. To maintain a constant temperature, the body needs to turn on the device with the same speed. Several evacuation process energy for your body. In general, the most important is the heat conduction in the air in contact with bare skin. If you are not a hat, wearing a convection of warm air rises vertically from the head like a feather from a chimney. Your body also loses energy by electromagnetic radiation, exhale hot air, and the evaporation of sweat. In this problem, the attention to another channel for energy loss: the moisture in the air. Suppose you breathe 30 breaths per minute, each Assuming a volume of 0.600 L., dry inhaling and exhaling air, the air at 37 ° C in water vapor with a vapor pressure of 3.20 kPa. The steam came from the evaporation of liquid water on its body. Model of water vapor as an ideal gas. Let us assume that the latent heat of vaporization at 37 ° C is the same as heat of vaporization at 100 ° C.Calculate the speed at which the energy lost exhale moist air. His answer, in W.
