Hydraulic jump Definition and 11 Threads

I have 90% of this done. When i looked in my manual i noticed an odd jump they made and i don't get why. that is where i need the help V1(b1h1) = V1(b2h2) Im solving for h2. What i can't figure out is what to use for the base measurement of the cross section of the water. i have no idea how...

Hi guys, I've been doing some light reading on hydraulic jumps. For example: So I've been through the basics, super critical to sub ciritcal etc: https://en.wikipedia.org/wiki/Hydraulic_jump So far I understand that the jump occurs at the two points either side of the critical depth, like we...

Sorry for the poor image... A better picture can be viewed here https://www.dropbox.com/s/uyi01l27vu2fwyw/96.png?dl=0 I don't understand the assumption in the red box... If I don't ignore the atmospheric pressure, F_1 = integrate from 0 to h_1 (ρg(h_1-z)+p_a)dz = 1/2 ρgh_1^2 + p_a*h_1, similarly...

Homework Statement http://www.brighthubengineering.com/hydraulics-civil-engineering/55054-open-channel-flow-basics-hydraulic-jump-calculations/ In th earlier part of this notes , i was told that the The hydraulic jump is an abrupt transition to subcritical from supercritical flow. but , in...

Homework Statement The question is stated here, though I'm happy to repost but they include a picture. I should say this is not homework, I'm doing problems for practice. http://web.mit.edu/2.25/www/5_pdf/5_04.pdf Homework Equations Conservation of momentum/mass The Attempt at a Solution...

Dear Fellow Engineers I'm having an issues with my calculations. This case concerns a open channel flow that start off being supercritical on the left and turns into subcritical flow after a hydraulic jump. Given: Volume flow rate Q = 0.16m^3/s Width of the channel b = 1m Resulting...

Hi, Homework Statement I'm doing some research into the hydraulic jump and was wanting some help in calculating the impact force. Hydraulic jump is a phenomenon to do with the turbulence of the water - it is the 'ring' around the stream of water when a tap is turned on Homework Equations The...

Hi, I'm doing some research into the hydraulic jump and was wanting some help in calculating the impact force. The equation I have found to use is: F = m g h / s I have the mgh, and was wondering what to use as the slow down distance. If you didn't know what the hydraulic jump was, it is a...

Please, say me what are shear forces. I've been looking for it because I was studying a phenomenon called hydraulic jump. In this example, are these forces caused by the cohesion forces?

These are the problems I have to choose between for a school project entering a competition. There are other problems but these are the ones I'm torn between. Hydraulic jump When a smooth column of water hits a horizontal plane, it flows out radially. At some radius, its height suddenly...
