In theory 3 inch pipe will flow the same cbf of air at 5 psi that it will at 20 psi the change is the density of the air flowing thought the pipe. Now the base atmospheric air cbf numbers are no long on the same plane as the 20 psi number unless you let the pipe fill a space (like a big room so it not compressed anymore )
But at this point it has nothing to do with building hp or a engine's air flow manners anymore |
All i was after was someone to give me some CFM numbers for the pipes using PV=NRT and asuming you have a maximum air speed of 250ft per second @ 20psi......(cant rember the veriables)
sorry if i didn't make that clear.
the reason i ask is i know STS guys have problems with the piping they run once they push past about 700rwhp. now if we know that a 3.0inch pipe can support say 125lbs of air per min then you know you can run a 3.0 inch pipe on a 1000bhp setup.
basically just trying to understand at what point, BHP wise, you need to run bigger piping.
