The difference between a 5.6K orifice and a 5.62K is only .20 GPM @ 100 PSI, so unless your calculating discharge at very high pressures who cares. Conversely at 1PSI the difference is only .01 GPM. See we start using computers that carry every calculation to 3 decimal places and that is the level of accuracy we expect, until you realize we started with a lot of assumptions, multiplied those by fluffy calculations, and then applied an accuracy of .001?

The real question though, as someone mentioned yesterday, is why are you being required to "prove" a pipe schedule system?
