Young Laplace Equation

An introduction to the Young-Laplace equation. One of a series of videos using lightboard technology developed at Imperial College London. I would like to thank Ollie Inglis, Hywel Jones and Lekan Ladipo from the Digital Media Centre in the Faculty of Engineering at Imperial College London for their help producing this and the other lightboard videos.

Masterful work to explain mean curvature intuitively in less than 15 minutes!

[@anubhavarora3282]

Sir your way of explaining is truly fabulous. I am grateful to you for providing such a quality content

[@user-ck2ew2oq7z]

Finally I understand the basis behind the 2σ/r. Thank you for sharing your knowledge, Professor.

OH MY GOD you are back

[@pizzalove4693]

Very nice explanation
Thank you for such quality content

[@DANGJOS]

You make it look easy, thanks!

Thank you sir❤

Hello, Professor. Thanks for your video!
Can you explain how to determine the curvature sign? My understanding is that if the curvature center is in the denser phase, then it is positive. Is that right?

[@BoffyBlunt]

I think you have this the wrong way round. We define the capillary pressure as the difference in pressure between the less dense phase and the denser phase, then positive curvature is when the less dense phase bulges out into the less dense phase (think gas and water).

​@@BoffyBlunt Thank you sir! I think I've got it.😃

Hi I need to ask something. How to reach you? Thanks

[@coldchickennoodles5575]

I still don't understand the equation, can someone explain pls

[@BoffyBlunt]

What specifically would you like help with? I can try to clarify points that you are confused with.

[@coldchickennoodles5575]

@@BoffyBlunt Thank you so much for answering. I just find the 'dv' part in the first equation you presented slightly confusing and the V=4/3(pi)r^3

[@BoffyBlunt]

@@coldchickennoodles5575 The dV comes from work - the work done from basic physics is PdV where P is pressure and dV is the change in volume. The equation V - 4/3(pi)r^3 is the equation for the volume of a sphere in terms of its radius r.

[@noodles8439]

I understand everything except that the professor can write backwards.
