I have a thin tube (4 mm diameter) sticking out of a small box (a bit larger than a matchbox). I want to use this tube to measure the dynamic pressure. How long must the tube be for the results to be reasonably accurate?
Intuition tells me the working end of the tube should be kept in the unobstructed flow, but I have no idea what it means in practical terms (and I want to keep the tube as short as possible).
I don't think I will be able to bend the tube without collapsing it (not even sure if that is a correct word in the context).
