Hi Daubery, thanks for your answer. I already have used hydraulic diameter because I needed to make the coupling of a circular 6" diameter duct from which the air come, to the rectangular duct where I need to work!. The idea was to have the same hydraulic diameters for both ducts avoiding to...
Hi,
I haven't got luck with my previous post (thread391-197659). One thing I need to know is the heat transfer coefficient for a rectangular duct fluid (air) inside, three of the walls are isolated from the enviroment and the remaining is an isothermal wall. The Reynold number corresponds to a...
