The Graetz number, Gz, is the reciprocal of a Fourier number, Fo.It is mainly used in calculations for steady flow, in which the time t r (the residence time of the fluid in a heated or cooled portion of a channel) is usually expressed via the length L and the … WebD. As a general example of how dimensionless numbers arise in fluid mechanics, the classical numbers in transport phenomena of mass, momentum, and energy are principally analyzed by the ratio of effective diffusivities in each transport mechanism. The six dimensionless numbers give the relative strengths of the different phenomena of inertia ...
