Assume the muscle is 37C and is separated from the outside air by layers of fat and skin. The layer of fat, at a particular location on the skin, is 2 mm thick and has a conductivity of 0.53 W/mK. Finally, the outermost epidermal layer is 0.1 mm thick with a thermal conductivity of 0.21 W/mK. How much heat is lost per unit area and unit time if the ambient air temperature is 0C?
