There are people who are very knowledgeable yet can't dumb things down for the layman, but you sir have a gift of teaching /explaining your explanations are simple and clear.
Thank you so much. I was having trouble grasping the equation, but you really broke it down to an understandable level. You help make physics enjoyable, much appreciation.
I think i remember my ordinary diff eq proffessor telling me Bernoulli's equation had applications in calculating blood flow. Its possible it was airys or legrange's he was talking about but ODE's can be applied to many different fields
Although it's been 5 years since this video was made, but it will still a reference, in five minutes I learn what I did in 5 years. That what you have when the instructor knows what he's talking about, he can explain it simply. Really great job.
Sir, great explanation! You helped shed light regarding Bernoulli's equation. Although, for the sake of other viewers, can I clarify the following? Around 8:00, shouldn't (0.5)(1000)(0.9^2) be equal to 405, not 1620? Also, the unit for the density of water should be kg/m^3 (instead of kg/m^2). I know those might just be typographical, but it's better to have it corrected right? Thank you!
@@Karim7097 I know you commented ages ago... But I'm wondering if you could help me? I got 88.625 kPa I had 129000 + 15680 + 405 = 145085 And on the other side I had P1 + 37240 + 19220 = P1 + 56460 So I did 145085 - 56460 = 88.625 kPa Any ideas why my number is slightly off from what you've said?
@@mahesv75974 He changes 129kPa to 129000Pa (same as you'd change kilometres to metres) at the start of the equation so the answer is 88625 Pascals, or 88.625 kilo Pascals (Dividing by 1000 ).
Amazing explanation! I never though to apply Bernoulli's equation to a ball moving through air, as I didn't know that air had the properties of a fluid even though it's a gas. I actually came here in my mission to learn how airfoils work and how air speed affects pressure. Thank you!
Wow, you really explained that in an intuitive manner, and very quickly without any fluff or anything, but still kept it interesting. Great video, thanks!
A very good video thanks. You explain the concept, with examples, clearly and concisely. You don't go too fast or too slow, no ums and ahs everywhere, and no PC text-to-speech.
I am retired now but still an avid learner. How I wish UA-cam existed in my day. I studied to pass exams but the many lousy teachers and lecturers I had made it all seem so difficult. Thank you very much.
I'm amazed by the marvellous efficiency and intelligibility of this video, honestly. 7:10 Just got a bit confused by the density of water where the unit is Kg/m^2 instead of Kg/m^3
It depends if you are in 2D or 3D. He seems to have kept everything in 2D so everything is normalized over the depth, hence Kg/m^2 is appropriate here. In a 3D setting you would of course use Kg/m^3.
what i dont understand is how in bernoullis equation P1 is different from P2, when Pascal's law states that pressure change occuring at one point is the same at another point. Take two points A and B at the same height like in the first example(3:10), the pressure there will be the hydrostatic pressure which will be the same cause of same height and the pressure that the you apply, so if the pressure from point A is transfered to point B how can P1 and P2 have different values?
throughout the whole video i was expecting the actual bernoulli's equation to appear, because everything you were talking about was pretty self-evident and i recall bernoulli's equation to be harder to comprehend. i had to open the wiki to make sure it is actually the same thing
when you go for the unit analysis of the last arrangement of equation at 6:02, it is rather pressure equivalent of the different type of energies (e.g. pressure equivalent of potential energy and by the same token pressure equivalent of kinetic energy). Perfect video though
Amazing explanation sir!!! It's just wonderful. .......................................................... Thanks for uploading such an incredible video!! so informative !! Thanks again
great work to sir Bernoulli. even if he died but his principle will never die. we use it even in medicine especial in anatomy and physiology .when blood stream reaches in constricted area of vessel the velocity increases but total mechanical energy remain kept constant.i am a medical scientist from RWANDA.
thanks for the video Mr. Anderson. Just wondering where you got the 1620 from in your calculation at 8.02 isnt it supposed to be 405 instead. since 1/2 (1000) (0.9)^2 = 405 ??
Thanks! this video was very helpful for understanding this concept. I liked the visual demonstration and the calculation you went through. They explained everything in a concise yet comprehensive way.
Thank you so much for your video! I am studying for my MCAT exam coming up next month and this was helpful in comparison to my MCAT physics review book. So far the book has been easy to follow except on this topic. Your explanation literally saved me a lot of study time, thank you again!
P1 and p2 are also known as static pressure. Highest at the very center of the tube. When we talk about pressure, that's what we refer to most of the time
If a tube is conected to a compressor on one end and opened to the atmosphere on the other end, and the compressor injects a fluid at 40 psi, will the tube walls be subjected to the same pressure along the whole length of the tube? or is this pressure just to move the fluid? will the walls expand due to the 40 psi? Bozeman Science Thanks for the help
Since you are an EXCELLENT teacher I saw in one of your sheets, for rho= kg/m2, acc to me it has to be kg/m3, to get all the units correct. But hey,only lots of respect the way YOU teach!!
Very interesting, but what if you have a "Y" shape pipe will the equation be P1+Potential energy+kinetic energy = (1/2 P1 + 1/2 Potential energy + 1/2 kinetic enery ) + (1/2 P1 + 1/2 potential energy + 1/2 kinetic energy).!!!
I'm a bit confused. Pressure is inversely proportional to Area. Then according to Benoulli's principle, why does Pressure decrease on decreasing the Area? Someone please help!
2:15 pressure p1 you explain as pressure pushing on [any] point within the fluid... Is this the same pressure that presses against the tube walls? Appreciate any thoughts, I have to understand this
the ball analysis is the same as aircraft wing since the upper surface is bulged more , it creates higher velocity so low static energy and viceversa for the lower wing surface. so this lifts the aircraft among with another factors.
Wow sir, thanks for helping in understanding this topic. I would like to know what kind of application did you use in this part of the video 4:30. Thank you so much
Hi Bozeman Science, Paul Anderson and Team, Thank You for your explanation of Bernoulli's Equation. It helped me sort out that rho=Density, and the potential and kinetic energy variables of the equation. Oh well back to the Pump Test Stand..... I'll pass the information along to other members of my Pump Unit Assembly Team.
If I had to go back to engineering school and do it over again. I would just take the text book, look up the chapters and then go to youtube and watch the video on the subject. UA-cam makes learning so much easier.
In horizontal tube pressure is applied by a piston for example. In a vertical tube, is the pressure energy is due to gravity and potential energy is also due to gravity? In vertical tube gravity is responsible for both potential and pressure energy?
Where do you see a need for conservation of energy confined to water in your ship example? Have you tried slapping a side of a pool with your palm? Did you feel any additional force smashing your hand on the wall?
5:28 I have a question. The milk coming out at the bottom hole did not come from the top. Doesn't each "milk molecule" need to come from the top in order to accrue kinetic energy? The milk at the bottom hole is already there; when you poke a hole at the bottom, the nearest milk molecule to that hole comes screaming out. It doesn't come from the top.
All the molecules in the container are pressing on the one at the bottom with their weight, transfering their energy on the one at the bottom. I hope this helps, its hard for me to explain this in english.
@@mihaelurh8372 How would be quantify that with an expression? I'm comfortable with MGH = KE (at the bottom) but we can't use that here. Sum up the mass of the fluid above the molecule that is about to leave the bottom hole?
Im pretty sure that equation still aplies (I miggt be wrong). You also have this: HG × Density = hydrostatic presure (presure at the bottom). This is the part of the bernoulis equation that has to do with changing of height. It's very useful to know.
I have a question, doesn’t high pressure want to be in low pressure? So the baseball will go down, because my teacher taught me in Bernoulli’s principle that when a plane is about to fly, there is fast air on top (low pressure) and slow air on the bottom (high pressure) of an airfoil. So the slow air automatically wants to connect to the fast air which pushes up the airfoil and makes a plane fly. And you need thrust and lift for a plane to take off and fly. So slow air is on top and the fast air is on the bottom of the baseball which makes the slow air automatically connect to the fast air which makes it go down right? I’m in grade 6 and I’m tryna be ahead of my class and be the best, so please explain to me how Bernoulli’s equation works in a simpler way that a grade sided can understand. I hope you can help me to be the best in my classes. Thank you.

I was just about to write the exact same thing. This is why I skip lectures sometimes. So much extra time.
