Anyone ever come across a website that will help calculate the size of pipe required for airlines in order to have a given pressure on the other end? For example, I have a 400' run of pipe, tied to a compressor tank, pressurized to 100psi, and I want to be able to have the 100psi at the end of the pipe run, so what size pipe do I need in order to obtain this?. The values are just for example, but gives the general idea of what I am after. _________________________________________________________________ Tired of spam?
