How Siphons Work: The Hydrostatic Equation

insta: @profbriankirby twitter: @profbriankirby A siphon is just a tube connecting a reservoir of fluid to an outlet which moves fluid by gravity. However, siphons can be counterintuitive at first because they are unpowered yet can move fluid against gravity over the raised edge of a container. And whether they work is all a function of in what order you do stuff -- do you take your thumb of the end first, or lift the hose up first, etc., etc. And who picks up a length of hose and immediately thinks wait -- gravitational potential is, by definition, path-independent, so the fact that the fluid goes over the edge is beside the point. How fast fluid moves in a siphon is a pipe flow problem suitable for the later part of an intro fluids class, but if you just want to know whether it will work or not, that can be answered using only hydrostatics, which is usually the start of intro fluids. What is interesting about it is that it forces us to use the integral hydrostatic equation along multiple paths (the same is true to understand a manometer). This video series is called "Professor Kirby's Fluid Mechanics Kitchen" because when we started recording it, Covid had just shut everything down, and I though I would have to record everything in my kitchen. And I had just redone my kitchen and the view of the kitchen from the cabinet kind of looks like a TV cooking show, and I thought that was funny. But instead of in my kitchen, this video was recorded in the Bellis Fluid Dynamics Lab at Cornell. Lectures are from Cornell University Mechanical Engineering 3230 - Introductory Fluid Mechanics. For reference information, especially how I teach it in MAE3230 at Cornell, see "How Fluids Work", Brian J. Kirby at Amazon: https://smile.amazon.com/dp/B09FRYGMVW. The music in the series is the music I listened to when I was doing my fluid mechanics homework back in the day. In this video, it is supposed to be Underground Kingz "Pinky Ring" and Aesop Rock "Kirby", but it isn't really Underground Kingz because I couldn't find a sample w/o profanity or slurs so instead Patrick Wick slowed Curtis Mayfield "Future Shock" down to 92 bpm since that is all the Underground Kingz production team did anyway. Looking forward to see which copyright infringement YouTube's AI thinks we made. I remember when I was 22 I thought the production on Pinky Ring was soooooooo cool until I realized it was just a straight bite of Mayfield. I mean, don't get me wrong, it's still great. Same for when I was 23 and heard DJ Screw's June 27 Mixtape until I realized it was just a Jermaine Dupri loop from a Kris Kross track. How is it that you just slow it down 20-60 bpm and then it is so much better. Also vis a vis Aesop Rock, I think "Kirby" is a fantastic name for a cat. I would have pushed for one of our cats to be named "Kirby" if it weren't for the obvious confusion that that could lead to. I feel like maybe I veered a touch off topic here. THERE IS NO EDITING PROCESS IN THE TEXT DESCRIPTION. Siphons!
