Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm working on a calculation of flow through a rectangular duct and I'm assuming I'm in the Stokes' flow regime (Re<<1), but I also want to experiment on this system and I was wondering if anyone knows until what Re-number Stokes' flow is still a good approximation (and how good, i.e. in percentages error): Re<0.1, Re<0.01 ?!

Does someone maybe have/know a scientific paper or book on this?

Thanks in advance,

Michiel
