This should be an easy problem, but I can't find the right portion of my brain or other reference materials!
A colleague asked me how much air would flow from an open 1-inch pipe if the pressure at the opening were 90 psi. Can someone point me in the right direction? I am thinking I just use the configurational loss in velocity heads for a plain end and back calculate the flow, but I am not sure if that will get me to the right place or not.

Bob:
90 psi (gauge or absolute?) at the end of the pipe and discharging to the atmosphere at 14.696 psia means that the air flow will be choked (i.e., at sonic velocity):
(1) Go to www.air-dispersion.com/source.html <== click here
(2) Select either metric or USA units
(3) Then select "Gas discharge from a pressurized source"
