Depends on different flow conditions ( laminar, turbulent, shapes of entrance, etc . ), the Nusselt number has different dependence on Reynolds number, Prandtl number and the friction factor of the flow.

Ashok Malhotra and Kang ( 1984 ) showed through calculations in a circular pipe that the Turbulent Prandtl Number is not close to unity but rather a strong function of the moleculer Prandtl number amongst other parameters.

The Churchill Bernstein equation is valid for a wide range of Reynolds numbers and Prandtl numbers, as long as the product of the two is greater than or equal to 0.2, as defined above.

Computed results in form of tables, graphs and figures for a fluid with Prandtl number = 0.71 with Rayleigh number ( Ra ) ranging from 10 3 to 10 7 are available in the literature.

Note that whereas the Reynolds number and Grashof number are subscripted with a length scale variable, the Prandtl number contains no such length scale in its definition and is dependent only on the fluid and the fluid state.

At the base of the Sun's convection zone the Magnetic Prandtl number is approximately 10 " 2, and in the interiors of planets and in liquid-metal laboratory dynamos is approximately 10 " 5.

It is a strong function of the molecular Prandtl number amongst other parameters and the Reynolds Analogy is not applicable when the molecular Prandtl number differs significantly from unity as determined by Malhotra and Kang; and elaborated by McEligot and Taylor and Churchill

Nevertheless this complicates the problem of launching jets : strong concentrations of magnetic field are required at the inner regions of the disc in order to launch jets, but a magnetic Prandtl number of order unity causes the field to diffuse away faster than it accretes inward.
