Reynolds Numbers and Turbulence (Fluid Mechanics - Lesson 11)

A review of the meaning of turbulence, and calculation of the Reynolds number for fluid moving through a tube. Focus it given to the concept's relationship to the heart murmurs, as well as the theoretical benefits of breathing a helium/oxygen mixture called Heliox.

I actually laughed out loud when you said "You'll never need to do that unless you're a Mechanical Engineer", because that's exactly what im doing. Im using your videos to brush up on my fluid mechanics for a ME Exam, you explain the concepts so simply and clearly its great, and seeing them in the context of the body instead of just the computational crap that our textbooks have us doing is really refreshing and helps keep it relevant. Thanks for putting the time forward to do this, Its helping at least 1 future ME haha

Ryan, I'm glad you're finding the videos helpful. Sorry they are aimed at health care professionals, so I skip over serious computational stuff or unusual physical scenarios, and instead stick mostly to general concepts and every day examples (at least every day in the hospital). I've always been an engineer at heart, but fluids were among the more challenging topics in undergrad. (i.e. you have my sympathies!)

+Strong Medicine may i have your sympathies too? :)

[@michaelngan99]

"so I skip over serious computational stuff" Thank God that you did, to keep the video clear and simple.

I am a Chemical Engineer ... and that's exactly what I'm doing (Flow assurance )

[@aclearlake6210]

You are hilarious. Professional explainer, but still fun to watch your videos.

[@abdullahtayeb9406]

i love you dr Eric thank you for your nice informative videos.i am from kurdistan iraq.

[@beaufry8552]

Cleared up all my questions, plus very cool! Nerded out lol

[@com.tricks2390]

great video, learned easily, thanks

[@s0520]

u saved my life。 thx for the explanation.

[@nihankhan1]

Thanx a lot for this amazing concept

[@avyakthgandhavalla3094]

the best i understood about reynolds number is just here...
than in my mechanical course...thnq so much....

[@vvvirgiliooo]

Thank you very much. saludos desde Chile.

[@StrongMed]

I'm very sorry - I haven't gotten to it yet. I'm working on the last handful of videos on electrolyte disorders, and will then try to come back to it! (may be a couple of weeks...)

[@medicogirl1783]

I'm aiming to get into a medical college this year, and your videos are extremely helpful!! thank you!!

[@KevinSmall]

Your videos are awesome !! I cannot find the video on Surface Tension :(

[@sloanestenson2347]

please help me understand the difference between wanting to increase diameter to decrease turbulence in an asthmatic and the earlier stated relationship between increased diameter and increased turbulence?

[@Hikarinara1217]

Thankyou again! I am a junior in high school from cali:)

[@martijngroenendijk3146]

Dear Sir,
First of all many, many thanks for your inspiring way of lecturing and videos. I assume that the viscosity of Heliox resembles that of Air or is bigger? Other wise you decrease the density but run into another problem if the viscosity of Heliox is less than that of Air. Why, apart from technical challenges, does Heliox not contribute in the treatment of Asthma?
yours Sincerely,
Martijn Groenendijk the Netherlands

[@MaykonSantini]

That was awesome. Congrats! I am a mechanical engineer in medical school now.

[@Kencan254]

Does provide formulas in the test e.g. Bernouli's formula etc?

[@asimupreti1515]

How did that happen?

[@MaykonSantini]

@@asimupreti1515 frustration with engineering and willing to become a physician 😂

[@Dinasaurous]

There’s something I’m curious about, so far which do you think is harder medical school or engineering

[@MaykonSantini]

@@Dinasaurous honestly both are hard. Usually people who get along with medicine wouldn't get along with engineering. In medicine, even though there's a lot of logical thinking, there are many things you just have to "learn by heart". It can get pretty annoying for people who don't have this ability well developed. On the other hand, the long and complicated calculations of engineering, aside with the terrible classes we usually have, can turn it into a hell as well...
So it's really personal. For me, I found medicine to be more difficult. It's important to bear in mind that medicine is very physically challenging too, due to long work hours and lack of sleep.

[@allaamrauf8214]

Chemical Engineering student here. We are often required to calculate the Reynolds Numbers too.

[@user-rz6jv9te7e]

nice work

[@KevinSmall]

Its ok take your time but just know that we appreciate your videos

[@davaocity659]

Just a comment, murmur is caused not by increased turbulence but the increased velocity that increases the turbulence. In the basic level of blood flow which is pulsatile and turbulent. Otherwise, an excellent video on turbulence.

[@tomcruise9317]

Sir let it be what happen to vessel if blood flow in turbulance other than murmer

[@colinmiller9173]

"and other scary sounding terms"...

[@016632]

im trying to learn crap fast for final and you make these time consuming fucken intros!!!
