WebSep 12, 2024 · Heat from the skin is required for sweat to evaporate from the skin, but without air flow, the air becomes saturated and evaporation stops. Air flow caused by convection replaces the saturated air by dry air and evaporation continues. Example 1.7. 3: Calculating the Flow of Mass during Convection. In general, the study of heat conduction is based on several principles. Heat flow is a form of energy flow, and as such it is meaningful to speak of the time rate of flow of heat into a region of space. • The time rate of heat flow into a region V is given by a time-dependent quantity qt(V). We assume q has a density Q, so that q t ( V ) = ∫ V Q ( x , t ) d x {\displaystyle q_{t}(V)=\int _{V}Q(x,t…
