The following is the only information that is given at this point in time:(adsbygoogle = window.adsbygoogle || []).push({});

Air flow through SS SCH40 1" pipe (ID 1.048"). Pressure required is 80 psi at the discharge point. Assume supply pressure is 100 psi and unlimited in quantity at a constant pressure, supplied from a tank. The pipe will discharge to atmospheric pressure.

I can't seem to remember how to determine how to calculate flow rate or velocity of the air based only on these values. I feel that I need more information to be able to calculate equivalent length at the very least, but even assuming a arbitrary length, I am having problems on figuring out how to approach this problem.

Any help here will be appreciated. (switching gears from chemical reactions to this stuff at 4pm is killing me)

I'll try to check back and answer any other questions so that I can get a quick answer.

Thanks!
