CEEN 341 - Lecture 9 - Flow Nets

[@ariely7601]

Thank you so much Dr. frank,this video is way much better than my Professor’s two hours lecture

[@bellaroba]

Thank you so much for this lecture and all other ones on the playlist, Dr. Frank.

[@bardhim1890]

Thank you very much for this lecture Dr Frank

[@taylordayton5570]

This video is so sick!

[@uSeeGeo]

great lecture! very-well explained.

Step by step video solutions of civil engineering questions

Hi, I know that one needs to ensure the areas or cells between flow lines and equipotential lines must be curvilinear squares in order to be able to draw a correct flow net. However, what is the scientific meaning behind it? Or it is purely empirical? Thank you very much

[@SaraA-kw4ti]

Thanks alot for this valuable lecture.

[@MasterCivilEngineering]

Good

Good

Hi sir thank you very much. i tried 10 hours trying to understand what my lecturer said but it took me 30 mins to und what you say!

[@harpergrace2510]

30:33 why did you count the boundary at the tailend side to be the 11.8 drop? The 11th equipotential line is within the soil layer NOT at the boundary.

i thought the music was out from my head phones at 09:15 while watching this video in my office. nice explanation.

[@mehranrezvani1241]

Thank you so much.

[@samkh746]

Amazing ..... Thank you very very much

[@YassirAsiri]

Good job. I learned alot even if im not E speaker due to your slowly talk

[@michaeltilly6208]

brilliant. thanks!

[@habtamukassa5015]

thanks GOD bless u more.........

Hello guys! Can you recommend any underground flow book with solved exercises?

[@broneilbetgovargez6120]

I wish I could access your powerpoint slides. but thanks it helped a lot.

[@Timbo63a]

I was a little confused by the part about the boxes being "square". Isn't it only required that the flow and potential lines intersect at right angles? Since the flow lines are of unequal total length, it would be necessary for the "boxes" to necessarily have different top and bottom lengths, but it would still be possible to draw the orthogonal intersections at right angles. One could use the average of top/bottom and left/right lines to imagine the effective "square". No??

[@officehours4028]

You aren't really drawing true squares, but "quasi-squares." You need to use a lot of imagination here, but the approximate horizontal distance and vertical distance through the center of the element need to be about the same. That is what I mean by "quasi-square."

[@nellvincervantes3223]

Question. How did you find the interval 15 ft for determining the uplift force under the dam?

[@harpergrace2510]

Nellvin Cervantes It all depends on you. It’s a personal preference, how much time time you can spare to do it.

[@harpergrace2510]

It all depends on you. It’s a personal preference, how much time time you can spare to do it.

[@harpergrace2510]

Please someone explain what am I missing when calculating for pore pressure at drop A and at E, I got a different value from what is shown in his solution. Drop A, = 1454 psf and at E= 315 psf

[@dibyendusarkar3622]

How do you know that how many flow lines or equipotential lines are needed to be drawn?

[@harpergrace2510]

It all depends on you. It’s a personal preference, how much time can you afford to do it.

[@meonchannel]

i need software download link

[@tofikraza5598]

How can I determine number of flow line

[@MasterCivilEngineering]

Find here

[@getachewsmur]

Good video

[@PardeepKumar-cd5qn]

sir how we draw flow net practically to get amount of seepage , please answer me sir (i am finding it from many days but i did not get it

[@MasterCivilEngineering]

Find here

[@badlibaba]

hi sir , g0od evening. how manage to get the 0.8H drop.? how you able to assume 0.8H? it maybe can be 0.6 or 0.7 or 0.9?

[@desertman2008]

@14:13 "Stop it. Get some help" micheal jordan meme. Good video btw

[@adane8059]

is 0.8 given? how can we get?

[@danielharvey1550]

it is usually given
