Pressure and flow speed relationship in wind tunnel

[QUOTE="russ_watters, post: 5619956, member: 142"] So this is homework? Or some sort of open-ended project/problem? You can use the compressible form of Bernoulli's equation to relate changes between pressure and velocity if you restrict the size of a test section (or any duct). But real world fans follow performance curves, so it would be very wrong to assume the fan could put out the same volume of air at a much higher pressure (even without considering the compressibility issue...). So unless something else is changed about the fan you would have to account for the drop in flow. So I would agree that we need more information to get a meaningful answer. [/QUOTE]
