In summary, the conversation discusses the confusion between the terms "Red" and "Re" in equations. It is clarified that "Re" with a subscript refers to the Reynolds number with respect to a specific characteristic dimension, such as the length of a flat plate or the diameter of a pipe. The conversation concludes with the clarification that "Re" in the context of pipe flow stands for diameter.

Hi, this is going to sound very stupid.
Is Red the same as Re?
Its just that in some equations, I have Red, and then in others Re. It might not sound like much of a problem, but I'd really appreciate if someone could clear things up for me. Thanks!

Reynolds number with a subscript usually pertains to the RE with respect to a particular characteristic dimension of an object. For example, in a lot of problems looking at flows past flat plates, you will see [tex]RE_x[/tex] for the RE along the length of the plate measured from the leading edge of the plate. Perhaps the usage in your case is the flow past a cylinder or sphere.

ohh right. Diameter, that's what it stands for. Its pipe flow. Thanks!
