An average person generates heat at a rate of 84 wwhile resting. assuming one-quarter of this heat is lost fromthe head and disregarding radiation, determine the averagesurface temperature of the head when it is not covered andis subjected to winds at 10°c and 25 km/h. the head can beapproximated as a 30-cm-diameter sphere. assume a surface temperature of 15°c for evaluation of ms. is this a good assumption?
