Dimension of temperature gradient

WebIn this case, the decay of the temperature profile in the surface vicinity becomes lower than that corresponding to some depth below the surface. This can also be seen from Figure 3.8, in which the temperature gradient (∂ T ∗ ∂ x ∗) is shown. The temperature gradient attains minimum at some depth below the surface. WebThe temperature gradient calculation for this construction predicts a temperature of 60°F in the eave space on a design day (70°F indoors/0°F outdoors): Assembly U-value (weighted average of at and between …
