If you are standing in a room that is held at a constant 75 F and your body temperature remains at a constant 98.6 F, compare the magnitudes of the different modes of heat transfer (convection, conduction, and radiation). Assume that the surface area of an average human is 1.6 m^2, the thermal conductivity for still air is k = 0.025 W/m-K, the air reaches the ambient temperature in 5 cm, the surroundings are at the same temperature as the air, the emissivity of a person is 0.95, and the heat transfer coefficient for a person is 22 W/m2-K. After doing this analysis, which, if any, modes could be considered negligible?
