DEFINITION The Biot number is defined as: : where:
\mathit{L_C} = rac{V_{body}}{A_{surface}}.
APPLICATIONS Values of the Biot number larger than 1 imply that the heat conduction inside the body is slower than at its surface, and temperature Gradients are non-negligible inside it. HEAT TRANSFER ANALOG An analogous version of the Biot number (usually called the "mass transfer Biot number", or ) is also used in mass diffusion processes: : where:
