Visit ilectureonline.com for more math and science lectures! In this video I will show you how to use Bernoulli's equation to find the pressure of a fluid in a pipe. Next video can be seen at: • Physics: Fluid Dynamic...
Proving Bernoulli's equation takes more that a few lines. The best way to think about it is the if P2 > P1 then at point 1 the fluid level must be at a higher elevation or the fluid velocity must be greater at point 1 (or both).
Mr. Michel Van Biezen, you have been my physics mentor for the past year, and haven't even known it. Thank you for your service, you are the true hero, and the OG, I salute you sir!
I have a final for fluid dynamics in 5 days, and I just came across your video. I’ve seen your lectures before and they help out so much. I’m done studying for the day, but when I wake up tomorrow, best believe I’m binge watching this. Thank you so much; you’re amazing
As someone who studied electricity I find learning about fluid dynamics fascinating and very useful. Thank you sir for providing this information so I and others can supplement my education. It is perhaps one of the most important endeavors our lives contain, the sharing and gathering of knowledge.
I wanted to take the time to thank you for your videos. I took physics I & II online over the summer and it was hard but with the help of your videos I got an A on both 😀
The derivation of this equation is actually very straightforward, and basically just the energy equation. It's the sum of the potential, kinetic, and extra energies, where the extra energy in this case is the pressure work. So you can set up the equation like this: m⋅g⋅h + 0.5⋅m⋅v² + p⋅V = constant From here, you can divide everything by the volume, which then gives you the final equation: ρ⋅g⋅h + 0.5⋅ρ⋅v² + p = constant
The Bernouilli's Equation-scene from "An Officer and a Gentleman" (1982) brought me here. But this lecture ofcourse, really puts the P in Physics. Although a certain Sheldon Cooper probably would beg to differ. Personally, I think this is an excellent lecture, of which I would like to see more of in the future. Preferably some lectures on the ever fascinating world of aviation and the dynamics of physics it entails. In the meantime, keep up the good work, Sir!
I don't know how I got here to see this video, but I don't regret playing it I learn something very valuable today, this is awesome when you turn your water and wonder how does it work? the answer is here. Bermoulli a genuine GENIUS
Hi, I just wanted to thank you, I have passed general physics in my university thanks to you. I thought that I can't do it but fortunately I did it with your help and I have graduated.
I'm Mechanical Engineer and you have explained it that even a person who don't have any physics background can understand it very clearly. You are a great teacher, those fellows are lucky to have a teacher like you. I have made a python program just to do the calculation so that I don't have to remember how a Bernoulis equation work. You just refreshed my concept thank you Sir.
Oh bro i really appreciated ur video it helps me a lot. and i could understand many things in fluid dynamics from this video im korean professor thanks a lot
Sir thank you for your videos. I first discovered this channel when I was in college and that time I was just a student of the civil engineering program. Today I am teaching as a License Civil Engr and I am still using your example. .
I'm refamiliarizing myself with this topic (I originally learned about it in Anatomy & Physiology via how blood pressure & circulation work) because I want to design an under gravel filter system for aquariums that minimizes "dead spots" in flow. If this video is an indication of the quality of your content, I've found EXACTLY what I need! Thank you!
I'm studying medicine, and I find the Physics in Medicine unit tricky at times!! Your videos have helped so much, and make Physics concepts so much clearer. Thank you Michael!!
I wanna thank you on all the lectures you giving us its very helpful. You have educative way to explain it so easy to students, It will be great if you can do some courses about Mass and energy Balances in chemical engineering.
The best all lecturers for this field, I remember my mechanics course in the semester 5, civil Engineering degree, in 2014, at that time I learnt this legend Professor Mechanics and hydraulics very well. I get these two difficult courses A plus, without attending for classes. Thank you Sir!
it's 11:30 pm here in italy, i never studied physics in my life and i'm not very good in english and math but this video just appeard in my suggested.. man, this is hypnotic: i understand everything and now i'm looking for part 2 of 7 thank you
Hi Mauro, Glad you found this video. There are 8,400 more videos on our channel. You can find them by going to the home page of "Ilectureonline" on RU-vid, or just type in: Michel van Biezen youtube and you will get to the home page. From there you can find all that you need.
Finished fluid statics, surface tension and buoyancy force in the previous couple of days Now studying fluid dynamics from you. You're giving me a lot of knowledge and saving a lot of time. 🙂❤
after al the time you spend in making these video's, it's the least i can do ;) got my exam next week and i get more convedent every day so ones again, thanks alot
Thank you for your time and expertise in fluid dynamics. I’m attempting to utilize Bernoulli’s equation to answer which water pump (gallons per hour) I will need for an aquarium room I am building. Being able to have the proper mathematical direction will allow me to analyze manufacturers claims versus my actual needs and expectations. I’ll be using this information also for my questions addressing if I should utilize multiple pumps and how much energy will be needed and/or consumed with a single large pump versus multiple pumps. This information will only be used for my aquarium room build and personal pleasure of the sciences, not to discredit any manufacturer or anyone for that matter. My physics skills (plug and chug) were proficient 20+ years ago however I’d like to wipe off the cobwebs, with some help. I do recall that when a variable (A2, h2) changes there must be a change to P2, V2 and/or v2. For some reason I vaguely remember that for every increase of 12” in height the flow rate decreases “roughly” 80 gallons per hour. I am not able to recall where this came from however I would enjoy knowing the why and how this is worked out. I will have multiple aquariums at different heights ranging from 1’ to 5’ above the pump(s). The pumps gph ability will be dictated by the total number of gallons and changes in heights of the aquariums. The gph demand is for the health of the fish and or plants. Knowing what flow rates will be expected at specific heights will provide me with the skills to make an educated decision as to which size of pumps I will use for my specific aquarium setup. Thank you for your time and any direction you may provide. Cheers - Breaux
Very clear explanation! I understood everything you were saying in this video. I wish you were my fluids professor :( *Edit: forgot to say thanks a bunch!! :)
@@MichelvanBiezen Hello Michel, sorry for the very late reply. Yes, I think that you are an amazing lecturer, the clarity with how you teach and I have been very happy to watch many of your lectures, I love to 'try to' understand physics as my line of work is engineering and love programmes on how structures are built and how they overcome problems, I loved the one on the Corinth Bridge with Richard Hammond. One thing that I have found difficult to understand is the 'natural frequency' of materials, components etc in relation to vibration, but again there are good videos online. Really appreciate the time, effort and willingness to share your knowledge with others. Thank again, Michel, you're a star.
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? Thanks for the help
This must be true on a universal scale as well. And eventhough it isn't, it gives me somethinv to work with. Love it! Absolutely. Bedankt voor de videos. Dit maakt mijn begrip een stuk beter
Bernoulli equations are conservation of energy statements in disguise. Pressure is energy divided by volume (look at the units). Density is mass divided by volume. So you can read the second term as mgh/vol. The third term is mass velocity squared / vol The equations basically say that energy in equals energy out.
Hello, Mr. Biezen! I find this video super helpful and I want to make sure everyone can understand and enjoy it. That's why I wanted to let you know that your captions are a little off. At about 0:27 the auto-captions say "Bendel's Equation" where they meant to say "Bernoulli's Equation." When you get a chance, could you please fix that? That'll help the 360 million folks globally who rely on closed captions to understand videos. Thank you, and keep up the great work!
If you use your cantilever for a piping systeme support , how do you calculate the dynamic charge of the fluid and then add the dynamic weight to the centalever calculation ?
I think I love your videos. Now I can understand. And I got this explained in my native language first, English is my second languge. Also I love that you use meters and not inches or whatever, tho...
Sometimes I wonder why I even bother looking at different RU-vid videos on physics not made by you. I understand everything so much better in your videos compared to others
Thank you for the confidence in our videos. We have 9500 on this channel so we cover most of physics and math with some engineering and others as well.
we have been using this formula (potential energy+kinetic energy+pressure energy). this formula often confusing me rather than the formula that you have given. in addition, how about the venturi meter, vena contracta and those orifice? is this formula could be use? Thanks Mr. Michel.
You are a living god for all students, your every explanations are Crystal clear, thank god for giving you!!! Thank you so much sir❤ . My one only doubt is why our lecturer can't teach as the way you teach????. They are getting that valuable teaching/lecturing job to earn money and destroying life of students . I think so!!!
Sir I really appreciate the effort that you put into these videos and they really help me understand the concept of physics but I have 2 suggestions, 1 could you edit some of the calculation ( cause even an 8th grader could do it and frankly values don't matter that much, concept does.) 2 could you please improve the listing of playlist they are tiny bit messy. Anyways thanks sir and have a great day.
Good day master. It's an insignificance that does not intend to subtract any merit from masterly explanations, but if you use the SI, I think you should indicate the symbol of second, in "s" That is, the speed unit would be in m / s.
Hi Michael! I have a fluid mechanic problem. I'm trying to design a kind of water valve with inexpensive materials as a first prototype, and I need to know the mass of the float and the buoyancy force need it to overcome the water flow pressure (F=PA) against the float of the valve. I did some math, could I send you a word.doc to show you the details? Please!!
Clear presentation, Sir! Of course in a real life there is always pressure loss in the pipe, therefore Bernoulli's equations as such is pretty useless when solving these kind of issues. Hopefully you could add some day one additional video where you would also take into account the pressure loss (i.e. the extended Bernoulli equation and Darcy-Weisbach). Thanks!
Yes you are correct. Just like anything else in physics we first learn the principles without friction, wind resistance, etc. Then we add the additional concepts when we are ready. We are planning a series on fluid dynamics in the future as time permits.
