Information
Defined to be the ratio of an internal resistance to an external resistance.
In the context of species or mass transfer, it is the ratio of the internal species transfer resistance to the boundary layer species transfer resistance.
- Bi = alpha_m*L/D_ab
In the context of the thermal fluids, it is ratio of the internal thermal resistance of a solid to the boundary layer thermal resistance.
- Bi = alpha*L/lambda
