In Experimental Methods, we discussed Bernoulli's equation, debated it's applicability to compressible flows and flows in general, then argued about the correct way to measure a flow's speed. One of the guys from AEDC offered the helpful opinion, that you just measure the pressure and you've got speed. True enough, but not enough to be true. So I corrected that you need a pitot-static tube, which measures dynamic and static pressure, from which the flow velocity could be calculated. I'm always right. Just remember that.
Anyway, we wasted 2 hours on the statements that "models have to be similar to the original" and "pressure can be measured." We didn't have anyone turn a pitot-static tube the wrong way in a flow (Garrett, Brian), mostly because we didn't actually measure anything, but the class wasn't exactly new material. Eh, if they want to give me a Masters without me knowing anything more than my Bachelors, that'll work, too.
Sonic boom. Another sonic boom. (They've been testing with a chase plane recently, so two sonic booms are the norm.)
It's lunch time now. I'm hungry. More tomorrow.
