WebJun 23, 2011 · The biot number allows you to make a judgemnet of whether or not there will be a significant temperature gradient through the object. If there is a low temperatuer gradient then the heat transfer equation reduces down to an easily solveable problem of temperature against time. The purpose of insulation is to provide a significant … The Biot number (Bi) is a dimensionless quantity used in heat transfer calculations, named for the eighteenth-century French physicist Jean-Baptiste Biot (1774–1862). The Biot number is the ratio of the thermal resistance for conduction inside a body to the resistance for convection at the surface of the … See more The Biot number is defined as: $${\displaystyle \mathrm {Bi} ={\frac {h}{k}}L}$$ where: • $${\displaystyle {k}}$$ is the thermal conductivity of … See more • Convection • Fourier number • Heat conduction See more The value of the Biot number can indicate the applicability (or inapplicability) of certain methods of solving transient heat transfer problems. … See more An analogous version of the Biot number (usually called the "mass transfer Biot number", or $${\displaystyle \mathrm {Bi} _{m}}$$) is also used in mass diffusion processes: $${\displaystyle \mathrm {Bi} _{m}={\frac {k_{c}}{D}}L}$$ See more persona mapping design thinking
