Fluid Mechanics Lesson 01A: Introduction

Fluid Mechanics Lesson Series - Lesson 01A: Introduction
This lesson is the first of the series - an introduction toto the subject of fluid mechanics. In this 10-minute video, Professor Cimbala defines "fluid mechanics" by first defining "fluid" and then defining "mechanics." Other topics introduced and/or reviewed are pressure, normal stresses, and shear stresses.

You're the goat, man absolute legend to have the guy that co-wrote one of the best textbooks on the topic making free and accessible course material online.

[markbrightwell]

This series of instructional videos is of super high quality, replete with scientific and engineering insight, and dense with worked examples. (I watched every video in the series in its entirety.)

[pomegranaterasberry]

I am absolutely ecstatic to have stumbled upon your videos today! I've been using your amazing book for so many years to learn and teach fluid mechanics to my students! Prof, thank you so much for the video! I'm beyond thrilled!

[ZyfGaming]

Thank you very much sir I find your explanations much more easier to understand compared to other courses here in youtube. In God we trust.

[abdallaelshennawi]

thank you so much Dr, I study your material from egypt and you are one of the best . thank you

[samuelalvesfreitas]

Thanks professor.
Hugs from Brazil.
I will present this channel to my students.
Thanks for all

[raymundoloera]

Professor Cimbala I just found your channel and love your textbook this is ideal because I was planning to review fluid mechanics all summer thanks !! God Bless you

[BladesAnglin]

Dr Cimbala, the Cedarville junior mechies sends their greetings and thanks!

[AmrGaber-hshi]

a 9-min video took me around 30 mins cause I write with you to remember stuff. I'm a mechanical engineering grad and this video was awesome

[Cidowu]

Thank you for such a great course Professor. God bless you.

[atillaus]

it is great to hear and see fluid mechanics legend here

[abhiraj]

Thank you for the simple explanation. Appreciate the effort 🙏👌

[Pakhavar]

I got the idea today of what is a continuous deformation. But why does it raise to the need of dx/dt over dy instead of dx/dy for shear stress? I know we can measure velocity more easily than change in length unlike solid. So, it is for just convenience.

Hello Prof Cimbala. Which video explains Moody diagrams?

[shane]

Hello, do you have any surface integration and/or divergence theorem lectures?

[frankiefresh]

Hello Prof Cimbala, Can you explain heat transport in fluids. Based on 2-box model of Stommel, but with ice in the Polar box and a tap in the deep flow pipe line. And what will happen to the temperature of the surface when it has a constant energy input (like the sun ) and you close the tap gradually . With ice in the polar box you have to deal with latent heat cooling, . Do we need to apply superposition principle in this flow ?

[Elias_za]

Great videos! hope you keep uploading videos like this

[rosemaryidoko]

What is the difference between constant velocity and terminal velocity

[ali.europe]

The concluding part is quite adequate.

[fernandomagallanesjr.]

No way, i get to hear from the author of the book himself, OG!!
