Hi, you defined diffusive wave approx. as a Steady non - uniform flow . you mentioned that this approximation would produce a this inflow hydrograph. This hydrograph depends on time but diffusive wave equation is steady. How it can be possible

Let the the fluid has uniform flow throughout the pipe. Is that mean there is no momentum change in the pipe?

Anyone know where the coefficient of discharge comes from… seems to be one of engineerings finest mysteries

🎉🎉🎉

Thank you Sir

Thank you so much

Good to see you're still at work! Best regards Terry J

great job

i wish you would be my teacher. amazing

EXCELLENT-- WHICH UNIVERSITY ? -WHICH COUNTRY ?

Please someone help me out, I have a tube well with 3 inches delivery and water is pulled by a 7.5 hp submersible pump system. What I am planning to do is to reuse the water force which falls out and to produce electricity or mechanical power. What output can be obtained and which system is more efficient, micro hydro turbine or a propeller.

Hi, Thank you for the good explanation. I'm personally interested in how you can use it to solve a nonlinear reaction diffusion equation. How would you go about analysis its stability in relation to the Von Neumann Stability condition? Thank you in advance.

👌👌👌

Was this video inspired by a publication or academic resource? I would be interested in learning more about the stability analysis!

Why is the momentum force in the opposite direction as the pressure force? Seems like they would both be acting in the same direction, no?🤔

Very good, detailed analysis. The figures and equations are beautifully rendered. Thanks!

Perfect, just explained in 5 mins what took hours to be taught badly in university.

Great video! But why can't I find anyone explaining 3-pt 1st-order FD?

Hello! Is there a way we could send you an email?

Hello, what is ubar in the bousinesque equation

Well explained Keep up the good work 👍

Shukran jidan!

what is bournolis ?

Is the beam warming scheme is implicit

What basics should i study more to understand this?

if we consider a 90-degree bend pipe, with initial conditions as follows: inlet velocity 15 m/s, no change in cross-section area (let's say radius of 0.2 m), and we only know outlet pressure is equal to atmospheric pressure. Is Bernoulli's equation satisfied? does it mean outlet and inlet pressure are the same? in that case, there's no flow?!

at 11:29 your wrote incorrect solution please review it. It should be (r - rho)*c(i+1),(j)

What a wonderful video!!!!!!

Would the vertical pressure force still be oriented downward if the curved pipe was facing down not up?

excellent explanations! I wish I had such an articulate professor when I studied open channel hydraulics at university.

this is amazing, thank you!

Thank you professor

Great video. Thank you

The last image looks just like B-Spline basis functions. Is my assumption right, or wrong?

Thanks a lot sir.

Very well explained. Thanks a lot!

Why is density not included in the Bernoulli equation?

Well presented, thank you Caspar!

It helped me a lot. Can you tell me how did you define initial distribution?

How do we determine the direction of pressure force?

such a nice video! well done!

hello, i stumbled upon a exercise that was similar to the last example but the curve was divided in half by two fluids. Would the resultant vertical force be the same?

The best 1d hydrodinamic equation explanation video!!!

u da mvp!

Thank you. I learned a lot from this video

Very good explanation. Thank you (again), Caspar.

Thank you. Well explained.

Very neatly explained, Caspar; thank you.

Great video

This is priceless!! cant be explained in a better way. Thank you for your effort.
