Let me give you a little bit more information of the background. This is a large compressed air system. The samples are to be taken at several use points. Each use point has it owns regulator, which during the sample taking process is set to 40 psi.
So how would I have a known volume? Would...
I need to find the volume of air (ft^3) for this sample. The air is discharged at 40 psi for 1 minute and the diameter of the pipe is 0.5 inches (Area = 0.001363538 ft^2). I think I need to solve for the velocity of the air (vel = sqrt(2P/rho), where P is the pressure and rho is the density)...
