Often used as an energy dissipation mechanism (e.g. spillway flows). Also may be used to get flow under a bridge (supercritical under bridge, then back to subcritical).
Just one question. Why we take chezzys and manning coefficient independent of fluid viscosity. i.e. According to my thinking, there will always be a fluid layer sticking to the bed (no slip condition) and the effect of bed roughness is propagated to other layers of fluid via viscosity. But both these coefficients doesn't have viscosity component in them. For example if I apply the Mannings equation for hot areas where water temp is at 30 Centigrade and in cold areas where the temperature is 5-10Centrigrade. In both, the case Mannings equation will yield the same Flow rate but I think the flow rate will be different in both cases for the same channel.. Please help me with this.
It would have been interesting to introduce a rotator and this inserted in the flow to see at what positions there is rotation. I would say that at the start of the jump there is a" stagnant " zone which is circulating rather than translating as all points elsewhere.
perfect illustration of hydraulic jump,couldn't ask for more,thanks a lot!
Thanks that was very informative. Excellent equipment as well.
Thanks for the video, it helped me to visualize the application of the equations!
Thank you!!!
Amazing!
beautifully explained !!!
making labs much more desirable and fun... thanks
thanks for the vdo.it helped a lot
well explained, thanks
excellent, thanks bro
thank you :)
Thank you it helped to recover my practical.😜
Nice video
thank you. :D
thank you very much
Very good. Congratulations.

awesome...
Thanks
great video, really enriching
Hi
Nice .thnx
How did u mark critical depth sir??
Duygulandırdı
How much is the rate of the hydraulic bank?
hi.. how did u make the gate at 5:05 min?
tooooooo gud
CV2020 brought me here
Dangerous stuff that water.
B is the channel width
@siamakghh2000 look up"Hydraulic jump, low head dam installation, and coarse sediment transport " on you-tube;)

Just like the kinetic energy correction factor, you can correct for whatever external conditions
How do we calculate the length along the channel where the jump will occur?
Bro you asking after 14years 🤣

What is "b" in the equation?
I assume g is the gravitational acceleration and Q the flow rate.
fujisaii channel width
I don't understand Y it s happening
what the .... does the f...ing glasses help!? Its just water!
standard lab protocol buddy
Safety first.
weird
thanks
thanks
