Thanks for the replys. I figured anywhere near Mach 1 speed are a bit too high...actually way to high. The best literature for air velocity speed is in the 80-100 ft/s (Compressed air pipes). I did find a few papers that have air velocity speeds in the 250-300 ft/s range but all in...

Hi everyone, I have a general question on fluid speed for air. What would be a reasonable design limit velocity for air? Assuming that it does not pass the speed of sound which can bring an whole set of other problems 1116 ft/s = 761 mph at sea level. Would 900ft/s be a reasonable...
