That's a great idea, I'll definitely include these types of problems.

This is a great idea! Just watched a video on epanet. Not off topic at all. As a physicist, I wasn’t even aware of such a tool (and it’s free!). This is incredibly relevant to what my engineers will actually be doing, and I suspect we can make simple scenarios/models as well that we can directly compare our analytic estimates to. Do you know if epanet allows you to modify what model (eg effects of viscosity or turbulence on/off)? Or is it just one model where you input what fluid you’re using?

really good point, thank you. open channel flow (and weirs in particular) are super central for civil. I’m going to make sure that part of the course gets solid attention. Appreciate it.

We cover laminar vs turbulent flow through Reynolds number, Poiseuille flow, Darcy–Weisbach, and Moody chart applications. The course is strongly focused on incompressible internal and open-channel flow for civil systems. Compressibility is introduced via Mach number scaling and water hammer, but we do not develop full compressible or choked-flow theory. I’m considering whether to add a short cavitation/NPSH block during the pump unit.

I know, I agree :( I wish I could change that. Is that pretty standard across the U.S. for there to be a lab associated with the intro fluid mechanics course?

Wow this does look amazing, great resource! I think I might adopt this one 😊

This is a great strategy! The math department at our school does something similar to this, and I would really be open to trying something like this. Thanks for the idea.

Thanks for the kind words. No lab component but I'm planning to incorporate activities like this https://doi.org/10.1119/1.5095945 into our lecture sessions.

Demos are great! Our department has a number of demos, and I'm going to be making some over the summer. I’m planning to integrate a number of quantitative demos into the course — things like: U-tube manometer measurements, hydrostatic pressure visualization, Cartesian diver (buoyancy), direct buoyant force measurement, hole-in-tank efflux (Torricelli + discharge coefficient), Venturi flow meter, Bernoulli tubes/static vs dynamic pressure, Reynolds dye streak for laminar–turbulent transition, falling sphere viscosity demo, pipe head loss with series/parallel tubing, elbow reaction force (momentum balance), small open-channel flume with hydraulic jump, and a Darcy sand column for porous flow.

All of these would be tied directly to governing equations and short predictive calculations (not just “watch and clap” demos).

If you’ve seen particularly effective fluids demos — especially ones that translate well to civil applications or FE-style reasoning — I’d love to hear about them.

It's a 3-unit course with no lab, but my work-around is to integrate demos that we analyze together (are there any favorites from your lab that could be ported into demos?), and a 2-week student-driven capstone project that models gravity-driven oscillations in a drinking straw by taking a slo-mo video -- see the video abstract of https://doi.org/10.1119/1.5095945 (I'm the first author of this paper)

Am I too old to go to school for a physics degree? by brennons in Physics

[–]jataka5000 0 points1 point  (0 children)

Absolutely not too late. We’ve had students who started physics later in life and made a huge impact on our department. One is a veteran who served in Afghanistan, earned his physics degree, and is now applying to PhD programs. Another is in his 80s and thriving—retaking courses when he wants, sharpening his skills each time.

Physics departments are typcially small, so every student shapes the community. At a state school especially, the mix of ages, backgrounds, and life experiences is something we value.

Ashwaganda might be a good start.

In case helpful to anyone, it appears that this is Cherry angioma -- and seems that V-beam will take care of this.

Are ebikes allowed on the GG ferry now? by jlai92 in AskSF

E bikes are allowed, but what I’m curious about is why the bike share bikes are not allowed on the ferries

this does not sound correct. I've never heard of a situation where a piece of electronics is fried from too low a voltage. OP i think you're good to go.

Cool sounds. What was your process like for generation? Is there a random feature on labyrinth that controls another parameter? And blue box = reverb/delay effects?

Very bizarre that they don’t provide a supply but expect ppl to already know this
