I thought it might be more appropriate to make a new thread dedicated to my experimentation with a 3D printed internal valve. I'm open to everyone's thoughts and suggestions, and I will answer as many que...

Dimensional Analysis to the rescue!

n feet per second * (3600 feet per hour / 1 foot per second) * (1 mile per hour / 5280 feet per second) =

Cancel your units, simplify, and you get MPH = (3600n)/5280.

So just quit bitching and listen to smiley face and freefall!

Protocol is just a standard set of rules governing how things should be done. How is dimensional analysis, in any way shape or form, bullsh*t? I figure the fewer things I have to remember, the better. Why should I remember 88fps=60mph, when I can easily derive it from what I already know (5280 feet ...
