Happy Friday. Interesting Engine Cooling thread has me thinking about an often misunderstood application of a relatively simple relationship; Total, dynamic, and static pressure. Hopefully the Mods will allow this as it is applicable to our endeavors.
The first picture is the test set-up. A fan is drawing air through the test chamber. Like our flying aircraft, it is outside or basically an infinitely large room. Water is the fluid in the manometer tube. For us nerds that want to overcomplicate things, don't; Flow is not turbulent, no compressibility, ignore friction effects.
The second picture has the relevant parameters (?)
If VAF is similar to the undergrad engineering population; one third will get the answer, another third will be wrong initially and then get the correct solution, another third will tell me I'm an idiot.
Feel free to make assumptions. Are there enough listed parameters to determine water column height X? If so, what is it?
