Document Summary
A 6 c increase in body temperature = 7 920 kj of heat. It would require 3 l of evaporated water to remove this heat. Convection and radiation use no water to dissipate heat. Shows weight specific water loss as a function of body weight. As you go to lower body weight, the amount of water loss increases. Smaller animals breathe more, so they lose more water across their respiratory system. Humidic animals are supposed to have high rates of evaporative water loss. Xeric can live in dry areas and have much lower water loss. Very little water loss, till it hits the melting point or transition point where you get a huge increase in water loss over a small temp range. This is where the lipid goes from solid to a more fluid state and the membrane loses its integrity. Warmer air holds more water than cooler air.
