It is named after the eighteenth century French physicist Jean-Baptiste Biot (17741862), and gives a simple index of the ratio of the thermal resistances inside of a body and at the surface of a body. The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. Biot number: Definition, Formula, Significance, For sphere Ability of a fluid to transport momentum by molecular means Pr Ability of that fluid to transport energy by molecular means = = Gases typically have Prandtl numbers in the range . Pe.
