Drugs, Dyes, & Mass Transfer: Crash Course Engineering #16

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force, discuss diffusion, and use Fick’s Law to help us model mass transfer.

Look how beautiful chemical Engineering is❤ I'm lucky to choose it as my field of study

[en]

I love this series, it inspires me to study harder in my field of engineering. Thank you CrashCourse for everything

[MalfunctonMke]

Ah... Fick's law. Gave me several good giggles in my german Material Science class :D

[fusionfallplayer]

I had flashbacks to my intro chemical engineering class! Great refresher on Fick's Law and diffusion

[Brainstorm]

Thanks for this great video. Was fun to think about these things again. They are also highly relevant to my field of neuroscience (see membrane potentials).

[bagussup]

I can clearly see the excitement drops from Dr somara after she explained heat exchanger into explaining this subject matter, I really cannot imagine if i am a mech engineer here to explain about chemical engineering material 🤣

[zowywet]

Yes, something we SHOULD learn about.

[camiloiribarren]

More lessons to learn and just a little better understanding

[hypersonic]

Keep going brilliant content! Thank you

I met a traveller from an antique land
Who said: “Two vast and trunkless legs of stone
Stand in the desert . . . Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed:
And on the pedestal these words appear:
‘My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!’
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.”

I was stupidly excited to see this video pop up in my subs. :>

[musicalenthusiast]

Crash Course Calculus would be interesting and helpful

[maxmusterman]

So the persons name was Fick? Now thats even more funny than Kant.

[danhc]

You can work and research drugs, dyes and mass transfer following the career of Chemical Engineering.

[TheSeriousPL]

This lecture sounded more like pharmaceutics than engineering, speaking from a viewpoint of a medic. Or am I just imagining it? Great video though!

[vaisnow]

I smiled wide as I saw Jesse and Walter in thumbnail

[unleashingpotential-psycho]

The word catalytic converter reminds me of Back to the Future.

[Felixkeeg]

I literally have Ficks Law in front of me on my table because I'm studying for my final exam in PChem

[lilylalune]

What age is this course appropriate for? I'm a student who is currently in 8th grade, and I'm struggling to understand a lot of what's going on.

[MrBlitzpunk]

Seeing drugs in the title i thought this was a new series of Crash Course Narcotics
