Our subjective feeling of hot and cold depends on the rate at which heat is lost through our skin. in this problem, we will model the skin as a flat layer of fatty tissue (k 0.3 w/m °k) with a thickness of 4 mm, separating an environment with a constant temperature of 37°c (normal body temperature) and the outside air. on a calm winter day with an ambient temperature of 0'°c, the convective heat transfer coefficient between the skin and the ambient air is approximately equal to 20 w/m2 °k. find the heat flux lost through the skin.
