Full Description

The quantitative evaluation of the many factors associated with the transfer of heat caused by the evaporation of body sweat has been a subject of major interest over the past three decades.

The purpose of the present paper is to develop a practical relationship between the resistance of clothing to water vapor and its transfer from the sweating skin surface. The heat balance equation for clothed subjects under the condition where all evaporation occurs at the skin surface will be validated by applying the fundamental mass transfer phenomenon of naphthalene sublimation rather than by water evaporation.
