Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawnmowers.
In this episode of Crash Course Physics, Shini talks to us about how fluids in motion are really, really, REALLY powerful things.

Watching the entirety of Crash Course has long been more valuable than some college degrees (From a learning standpoint. Good luck putting "RU-vid" on the Education section of your resume.). This is the future of education. It's much cheaper than than paying a college professor for every 20 students and maintaining a luxury 24/7 young adult resort. I've been mostly ignoring the physics videos, because I studied all of this stuff at university for my engineering degree. Engineering degrees are very overrated, by the way. I've been unemployed about 25% of the time since I graduated, and I was only making $40k a year with no benefits the rest of the time (yes, at an actual engineering job). Saw a job posting today asking for an engineering degree (and then some) offering *up to* $15/hr. That American Dream stuff? Bullshit. You may as well get your education from RU-vid.

@yeknomican 6 лет назад

Crash Course Physics vids are amazing and really underappreciated. I guess they work best when you're re-learning it or have some frame of reference, but they really tackled some deep concepts in quite possibly the most graspable and conceptually sound way possible for such a short format.

@geniusmp2001 7 лет назад

I can't help but think of the What If entry for "What would happen if one tried to funnel Niagara Falls through a straw?" "The flow rate over Niagara Falls is at least 100,000 cubic feet per second, which is actually mandated by law...A typical straw is about 7mm in diameter. To find out how fast the water flows, we just divide the flow rate by that area. If the result is greater than the speed of sound, our flow will probably be choked, which will lead to problems. (Math here) Apparently, our water will be going one-quarter of the speed of light."

That was so good!! I want more fluid episodes!! I once built a laminar-flow fountain for a maker-event, and despite having lots of Intro physics experience, Thanks to transfering colleges, I never managed to have a course that cover hydrodynamics; so I had to learn everything from a dry textbook. This episode made a lot of that stuff much friendlier. I want more! Don't go to boring old harmonic-motion next (Yeah, I know this is all recorded weeks in advance, and planned way earlier....but....Y'all know this series needs a 2nd season.)

What's true for water here, is also true for the air ducts ventilating your office or home. HVAC workers (usually) take great care to make sure the air duct's geometry remains constant through the entire duct. CAD programs are frequently used to help engineer consistent flow, and stamp out the parts on a plasma or laser CAM. (Source - Reconnected a Lockformer Vulkan to a PC and cut ducts for a welding shop during the recession).

@bhrisvfyapn 8 лет назад

There are two things Shini explains nicely but without showing connection: one is relation between cross section area and velocity in situation when there is active flow inside pipe second is relation between pressure and output velocity of flow. In other words that cool visual example with garden hose can be somehow explaned with #1 but if you try to calculate velocity of stream you might have hard time doing it with #2
