Or, … WebThe cooling effect of perspiration evaporation makes use of the very large heat of vaporization of water. This heat of vaporization is 540 calories/gm at the boiling point, but is even larger, 580 cal/gm, at the normal skin temperature. If the rate of evaporation of perspiration is gm/day = gm/hr. then the cooling rate is Q/t = watts.
