Problem: What is the Reynolds number for 1500gpm of 70 degree water flowing in a standard weight steel pipe with a diameter of 10 inches?
Approach: But what we do that, what we're actually going to find out is that the diameter equals 10.0 two inches.
Key step: What is the Reynolds number for 1500gpm of 70 degree water flowing in a standard weight steel pipe with a diameter of 10 inches?
Watch out: So the velocity is not known, but the volume flow rate is, and the diameter, we know it's a standard weight steel pipe at 10 inches, so we've got to l...
Result: Anyway, it's not too much trouble to look it up, so you may want to do it, and when you need to find the velocity, rather than having to do the work o...
