I had job interview question about how would I design open concrete channel and I mentioned this equation. Interviewer asked me what the value of coefficient of manning represents in terms of runoff and how that affects the velocity. I struggled because I forgot the equation formula and I said if n is in denominator, flow rate will be inversely proportionate and as well as velocity of the runoff as well after rainfall. I didn't answer professionally but now I look back I answered it below average...
Thank you for this video. Very helpful! I have a question though, Maam. Is the roughness coefficient a property of the material itself or it depends on the fluid flowing through, like does it change if it's water or wind?
Just to point out ft is rarely still used in England (especially for these kind of calculations), generally the metric system is adopted instead and the 1.486 value would be more commonplace in the US. That being said great video and really well explained :)
Hi, how do you find the wetted parameter of a circle? ex. when they say is full pipe flow vs a half pipe flow? and lastly how do . you calculate the slope when given the elevation of two stations and the length ?
Hello Andrea, I will try to post a video answering all your questions because that would be much easier than explaining it here. Thank you for watching and good luck with your studying!
i would like to thank you for your work
I wish someone was as good as you to make EEE videos!!!
Hello Mark, thank you for your comment and for watching. Also, what is EEE?

Hi kenza. Nice problem. I liked it. Could you solve one V-shape channel problem?

half pipe Area : pi/4*d^2*(1/2) and half pipe Parameter: pi/2*d
