Hydraulic Jumps

Lab Instruction Video on Creating a Hydraulic Jump

[@drakomist]

perfect illustration of hydraulic jump,couldn't ask for more,thanks a lot!

[@SoulsStride]

Thanks for the video, it helped me to visualize the application of the equations!

[@djkjjudi]

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).

making labs much more desirable and fun... thanks

CV2020 brought me here

[@ronakbhagora]

thank you very much

[@ChrisBence]

Thanks that was very informative. Excellent equipment as well.

[@sachinpawar6339]

Thank you it helped to recover my practical.😜 Nice video

[@eu_lury]

great video, really enriching

Hi

[@dilbagsingh4505]

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.

Just like the kinetic energy correction factor, you can correct for whatever external conditions

[@thedon639]

thanks for the vdo.it helped a lot

[@carmelpule6954]

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.

B is the channel width

[@torontogirl5868]

Thank you!!!

[@saeedshakarami6699]

Thanks

[@amanpreetsinghbrar6697]

beautifully explained !!!

[@MrDosSantos]

Very good. Congratulations.

[@Pushpendrasingh-xe6cr]

well explained, thanks

[@elispot17]

How much is the rate of the hydraulic bank?

[@j-paul4327]

Amazing!

[@brett03747]

How do we calculate the length along the channel where the jump will occur?

[@prannavbeetukoori4022]

Bro you asking after 14years 🤣

[@MrObliter8]

thanks

[@AnuragKumar698]

thank you :)

[@Hypzez]

what the .... does the f...ing glasses help!? Its just water!

[@EdgarSantana52]

standard lab protocol buddy

[@davedave6650]

Safety first.

[@L6FT]

What is "b" in the equation? I assume g is the gravitational acceleration and Q the flow rate.

[@IronMan-qi3yg]

fujisaii channel width

[@nairameam]

thank you. :D

[@sagarsrinivas7486]

How did u mark critical depth sir??

[@andyriyan]

excellent, thanks bro

[@riverlifeva]

@siamakghh2000 look up"Hydraulic jump, low head dam installation, and coarse sediment transport " on you-tube;)

[@avikzaman1]

hi.. how did u make the gate at 5:05 min?

[@EwanTBC]

Dangerous stuff that water.

[@sudharanis7616]

I don't understand Y it s happening

awesome...

[@eng.mahgoor]

Nice .thnx

[@akshatbisht609]

tooooooo gud

[@butolina]

weird
