manometer - Did you DIY or BUY manometer(s)?

Arguably the biggest flow benches ever built are actually wind tunnels.

If we are going to have a "mine is bigger than yours" argument, then you will need at lest several thousand horsepower to power the fan of your wind tunnel to play this game.

"Fan blades of Langley Research Center's 16 foot transonic wind tunnel in 1990, before it was mothballed in 2004."

When it comes to impressive wind tunnels, the link below will take you to a description of the North American Aviation (then North American Rockwell, Rockwell, Boeing North American, and finally, Boeing - 1997). The tunnel was referred to as the "Trisonic" because it would flow more than Mach 3 with a seven FOOT square test section! And it was used a lot of times at those speeds (including the Mach 3 B-70 program). The tunnel they let me use was 24 INCHES high by 42 INCHES wide and would flow about 50mph (~0.6M). :p

Rusty (the author) was one of the "icons" of the tunnel world!
