Bernoulli's laws were very helpful to me when I worked at a scientific instrument company called Tekran. We built a really cool inertial probe that was designed by my bosses, and I wrote the software to their specifications. One of the cool parts of our product was that it was volumetric, which is to say, the probe had to know how much of the exhaust gasses had been extracted as a sample, and how much dilution had been achieved, so all flows of clean (dilution) and highly acidic sample gasses (coal fired generators, for instance) had to be measured very accurately. The narrowing of a venturi and a differential and an absolute pressure sensor and Bernoulli's equations permitted us to figure out the actual volumetric flows. Pilots are familiar with this as well, because of the pitot tubes and the pressure sensor and the differential pressures helping us know how fast an aircraft is travelling by knowing how fast the air is moving over the airframe. It was some years ago that I worked at Tekran and I am still incredibly proud of what tekran designed; The technology they built is still in use to help in monitoring sources of mercury pollution, to ensure that public health, and environmental integrity (water and air quality) are protected. Bernoulli's equations have MANY uses, both in and out of aeronautical engineering.
@7:41 Acceleration is delta V divided by delta T. It does not depend on the current car speed. If you burn 1 oz of fuel in 1 sec you will get particular acceleration regardless of the current car speed. a=SQRT((2∗E/m)^2/t). Acceleration depends on Burned fuel Energy (E), car mass (M) and time (t). We can also replace Energy (E) with Engine Power (P) in the previous formula to get a=SQRT(P/(2∗m∗t)).
Wow, thanks Austin for giving us these insightful lessons. I really enjoy them just as much as I enjoy the powerful simulator you built. You have superior teaching skills. 💯
I second this! And I hope developers will update their past aircraft since there are soooo many that are coming out for XP12 right now that have to be run through Rosetta.
Austin certainly has aviation in His blood . A true businessman, pilot , educator, and I would certainly feel comfortable being in any aircraft with this man !
Brilliant² lesson, thanks for that very interesting post ... still not cool advertising for Tesla because of it's negative ecological and social impacts
Am I missing something? He stated at 3:42 that turbofan jet engines are designed with air going into a narrow tube then going into a bigger tube. But the air intakes of a jet engine are bigger than the compressor of the engine, right? Is he saying that the big fan blades that the air hits first acts to spread the air throughout the engine and somehow making the tube in the middle of the engine wider? I’m struggling to see how the air intake at the front of the engine is a narrower tube than the compressor and exhaust at the middle and back of the engine. Can someone please explain? Thanks!
I just looked at some side-angle photos of turbofan engines and it looks like the front air intake cowling is indeed a bit narrower (by a few inches) than the middle of the engine. I assume this is what he is referring to
Correct. It is actually narrower in the front and gets wider going back to the fan. Now I know it is only a few inches but here is a fascinating thing: remember, we are looking at cross-section area and area goes with the square of the diameter… So a small increase in diameter is a much larger increase in area than you might think.
I noticed the video posted after this video was deleted, an interesting video which was critical of a certain jet in favor of a certain prop. Is there a reason for the deletion or will this forever remain one of life's odd little mysteries? 😎
Hi Austin , really interesting video , I've heard of Bernoulli's law every since I watched Mythbusters as a kid and engineering documentaries it's great to heard about in this aviation centric video , also unrelated but I have noticed in XP12 , the strobe effect in clouds is missing
Hey Austin quick question about Xplane 12! I know you guys said you'll be able to see the depths of the water. Should that show the different shades and colors as well? I'm from the Bahamas and we really want that tropical look when flying around the islands!
I have heard that water turbidity ( how clear , cloudy , or murdky water can be ) is being worked on aswell as water masking , I find it slightly immersion breaking especially in some where like Portland Oregon the water is not cloudy enough and you can seen the bottom half of the seaplane floats in the water , it looks odd as you would only ever see that in clear tropic water.

I enjoy listening to anything Austin has to say. He is just brilliant and explains things better than most University professors. Just brilliant 👏
Same principle applies to how a lot of airspeed sensors work ;-)
Happy new year 🎉🎉🎉

I wish Austin was my science teacher. I would think the class would be fun. At least I graduated from school.
I really appreciate these explanations. Very well done.
X Plane 12 needs more videos like this one.
Added to the official VAEROSPACE inventory !!!!! .Austin is an angel from heaven .
Did cirrus get upset after totaling dissing their jet? 😂😂 Can't fing that video anymore

Great presentation. Thanks for this.
very good explaination
Hey I learned something new here, thanks Austin!
Austin can explain things so well!
Hey Austin, what happened to your Cirrus Jet vs Epic video?
Interesting science lesson. Thanks! Say, any news on when a new SDK will be available so we plugin makers can build for M1 Macs?
I second this! And I hope developers will update their past aircraft since there are soooo many that are coming out for XP12 right now that have to be run through Rosetta.
Sooooo... how much power should Cirrus add to their vision Jet to benefit from this effect and go a proper mach 8 🙂 ?
Hello, I have one question When Will the MCDU be able to use?
explain condition levet lowered in the lancair

As always, brilliant Mr Austin Thx!
Austin, you're a pretty cool bit of Human Ware. Rock on, my man! ❤️

Thanks a bunch.. So do you own Tesla Stock>>the product placement maakes me wonder. Cool er..Warm Jacket
i prefer thinking of helicopters and tilt rotors.
thanks from Austria for this physics lesson!
Bitte schön! ❤️🇦🇹

Nice Jacket. I have the same one :-) Hope your Roadster is coming soon (lol).
thank you very much from TURKEY❤
Five lanes going down to one lane? In my experience that means you get a traffic jam.
You will.. UNLESS everyone speeds to 100 mph in the single lane. Then, you would not!
In driving lessons and by traffic signs we're told to slow down when a buiding site with reduced lanes is ahead. Obviously wrong... : D
austin in the backrooms 💀
Brilliant lesson ... still not cool advertising for Tesla because of it's bad ecological and social impact
