Fluid Mechanics: Topic 7.3 - Conservation of energy for a control volume 

That's an excellent video! I'm revising fluid mechanics concepts to my work and your playlist is really really great! It's very detailed and well explained. Keep going with the good work and thank you very much for it! Greetings from a Brazilian ChemEng student!

my head hurts, but thanks for the video. Ill have to watch it at least 10 times to fully get it, but is nice to know there is a good resource to learn this concepts

Nice explanation,very helpful in a quick,but detailed revision.regarding from an mech. B.Tech student from IITB

Thank you so much. This actually makes everything clear.....you saved us from rote memorization.

Sir, thank you for your great effort for making these videos. They are awesome!

Thanks for the great lecture. I find it curious that the shear stress doesn't show up in the energy equation. You'd expect friction to contribute to energy loss.

Thank you so much for such a helpful video, amazing series

your videos are the best!!!!!! Very clear

Hello! If I have, for example, a heat source generating 80W into the diaphragm wall, the diaphragm walls is into the ground, the heat exchanged at the interface ground/concrete could give me the actually energy efficiency of the system? For example, if I need to extract 80W from the ground through this concrete diaphragm wall, can I find out how much of the energy I can actually obtain to say "My needs are 80W, but I can get only 60W from the ground"? I am studying geothermal energy (energy foundations as diaphragm walls) and I don't know exactly what's happening in the ground because the method I am using consist in treating the pipes within the diaphragm walls (which are in the ground) as heat sources, followed by measuring the exchange heat at the interface of concrete/ground. But I don't understand exactly what this means. I would really appreciate your answer!! Thank you!

I love these videos

kinda sus
