Thanks so much for saying. Your TA Indy is usually more of a "big picture" kinda kitty, but in this case of the Reynolds Transport Theorem, he's all about the details.
Your TA Indiana is just a regular kitty - no formal training at all - entirely self taught. For me - I was a nuclear power officer on submarines in the us navy. That was my first job after college. Nowadays, I have a phd in mechanical engineering, and I teach at Schreiner University in Kerrville, TX. Thanks so much for watching.
@@BrianBernardEngineering i would love some examples of an isentropic nozzle and its relation with static air temps at different points in the nozzle. How do the temps differ? especially, being isentropic (trick question?) Also, tie in the mach number at a specific point IN the nozzle. Want to see an example??
It's usually the difference in pressure that actually matters. Pressure inside something pushes outward, atmospheric pressure pushes inward. The difference is important since you are summing forces in the two different directions to get a net force due to gauge pressure. This is why you don't actually measure atmospheric pressure usually. Atmospheric pressures changes a bit everyday due to weather. Since we only care about the gauge pressure, it doesn't matter exactly what the reference points absolute pressure is.
This is such a well produced video, really should have more views!
That's very kind to say, thank you so much for watching.
A.M.A.Z.I.N.G video, love the enthusiasm and attention to each detail!

one of the best explanation i have ever heard,thank you very much am humble 🙏
You are very welcome
Ive been an engineer for about 3 years now, absolutely love it. Best explanation I've come across... what is your background?

Thanks, I watched this during the exam
I hope your exam was open book / open internet. Otherwise you may want to keep that to yourself :P
@@BrianBernardEngineering yes of course haha

Why do we use gauge pressure? And not the abs
