There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this video we explore the differences between these two flow regimes. We'll cover how Reynolds number can be used to predict which flow regime will occur for a specific set of flow conditions. And we will look at laminar and turbulent flows in pipes, and how the flow regime affects the pressure drop in a pipe. We'll also investigate why it is so difficult to simulate turbulent flow, and we'll look at some of the different Computational Fluid Dynamics methods which can be used to simulate it.

@SujalRajput10 3 года назад
I think its just a matter of content and time. It would have taken him hours to condense all this knowledge in a 15 min video. That's without adding the time taken in animations. In a real class this would not work unless you want to finish your 1 year course in 5 years. Plus most professors will take the time to make sure that at least 3/4 th of his class understands the topic. He will sometimes add questions in between the lecture to make students understand the lecture. And he has to do this for your whole academic year. So it's wrong to say your professor is worse than the narrator of this video. He is doing his best, with what he has.

nowadays professors are only focused on problem-solving. not a clear understanding of how the equation works, how the theory impact on real-life principles. that's why these types of videos are lifesavers. professors never try to put these types of effort into basic understanding. cuz at the University they only focused on the exam-oriented syllabus. not to disrespect the professors but in reality, if you want to learn more deeply sometimes you have to be disappointed in your professor

@abradablincoln3052 4 года назад
You do such a great job explaining engineering principles. Especially with your good quality and simple animations. I’m currently learning Fluid Mechanics, and this is easy to understand and interpret. I think you should really start your own online learning program in which you continue to teach these fundamental engineering principles. Like statics, mechanics of materials, structural analysis, fluid mechanics, dynamics, etc. Keep up the good work !

I've seen some of your videos and I can confidently say that even after graduating from university, I'm still learning much of the basics from your videos. You clearly explain theoretical concepts well without getting too convoluted and technical in the mathematics and equations. Thank you for your hard work. I won't be surprised if in the future, you would branch out to more specific disciplines such as mechanical, structural, and geotechnical engineering. I will selfishly request that you might do more videos on structural analysis and even possibly nonlinear analysis, haha. But please keep on doing more videos like this. This laminar vs turbulent flow video brings back a lot of memories from my fluid mechanics class even though I will no longer use them because I'm in structural engineering.

I love how he stated: "traditional engineering tend to be very math-heavy". This has been a HUGE problem for a lot of people including myself with the upper level engineering courses. Luckily we all made it through and have less than a year of college left to get through. Point im trying to make is this: Way too much of our engineering education is about mathematical modeling, equation solving, and calculating some parameter given other known parameters. This is all fine too learn but what is heavily, and I mean HEAVILY skipped most often is the actual physical science of why something is happening according to our observations of the physical world. Engineers come out of school and cant design anything hardly because they very little intuition of how the science actually works and most importantly why it works. Its not all about algebra, calculus, and matlab/python mathematics and coding. Colleges focus on this because its their way of 1, weeding people out of engineering, and 2, its one of the best way to create testing/quizzing for the class. Throughout my whole time in college I can probably count on just my hands and toes how often a conceptual question about how or why a physical phenomenon was even happening. Its alway math math math math, MATH!
