Hi! Dr. Wait. Millions of thanks for your lessons and sharings. Finding a source for teaching water management is so hard. Thank you very very much again.

I'm just curious if you had to purchase the WMS software package from Aquaveo or managed with the fee version?

Hi Isaac, excellent video! I deal with a special lining material (a combination of concrete + membrane). I wonder if you are familiar with Hydraulic Calculator of FHWA? The channel that we deal with has extreme high velocity that can reach 15-20m/s and the flow rate can be 50m3 / sec. Happy to know more on channel lining with flexible and impermeable membrane. This seems like a new way lining a channel nowadays.

Dear professor Wait, first of all I want to thank you for sharing your videos. I’d like to ask for a favor. I passed my FE about 3months ago, now I’d like to take my PE civil structural. Maybe you remember me, I commented in one of your videos. I’d like to ask you if you could reach out professor Michaelson, happens that he uploaded a video for structural steel design but there’s only one video, I’d like to see if is possible that he could upload or make accesible that playlist. This the only one video kzbin.info/www/bejne/n6HUk5Rsrrelaq8si=8uQGJnTxqmXSx9RY , I just need to see the column design in a frame lessons. I really appreciate your help professor. Thank you so much for your help. And please never stop sharing your knowledge.

Why doesn't he claim Medicare and Social Security withheld?

Hello sir , would you be able to derive a few equations for me for my up coming Exam ?

Hey, professor could i have your email address please ?

I'm using these videos to study for my PE as someone who did not study civil engineering in my undergrad, and this whole channel is a godsend. Thanks for all you do!

Hey, professor I appreciate your work very much thank you Will you repeat CE 434 - Water and Wastewater Treatment (Fall 2022) and share the full lectures?

greetings from indonesia and thank you for the fruitful video! if I may ask, can I calculate curve numbers without using the web service (since I'm not from US)? and is there any constraint or tutor on how to make the notepad for the soil type?

How much is your weimaraner cost for storm drainage. Thank you

Hello I am Aleksandar Katanić hydraulic engineer from Serbia I wont to thank you for all yours videos. I don't have too much design experience but your videos help me a lot knowledge should be free. GOD bless you.

thanks a lot

the random usage of winterplace as an example caught me off guard lol, best snowboarding on east coast

In calculating the effective interest rate, may I know why m is 4 rather than 3

Capitalized cost, I think p=Ai hence 😮am not understanding A/i

Hi great videoa i just have question I hope you answer it is 2.794 the normal depth for the 5.7 m wide channel

nice

Thank you for posting these. I'm doing this class at another school but with the same book examples, and was very confused about the units (or lack of) in the book until I saw these videos. Inclusion of the units is very helpful for students and in general.

Just passed my PE exam. The materials you posted have helped me tremendously especially since I've been out of school for 10+ years. Just want to say thank you so much, and please keep it going. :)

now i understand it thank you

Isaac you are a brilliant professor! Thank you!

Thanks

Dear Professor Isaac, I just want to thank you for your videos. You have no idea how important they are. I’m from Mexico, I graduated from school when I was 40 years old. Now I’m 48 and I recently moved to the US. I just passed my FE exam thanks to your videos, I want to thank you and professor Gregory for your videos. Pls let professor Greg I really appreciate his help. Thank you !!!

Request you to please share the spreadsheet

Dear Professor, thank you very much for posting the course. I wonder if you have uploaded "CE 331, Class 31"? I find it is missing. Thanks.

Dear Professor, thank you very much for posting the course. I wonder if you have uploaded "CE 433, Class 27"? I find it is missing. Thanks.

good video sir 🙏🙏

If the corrected Q is a negative number, that means that the direction is the opposite from the one that we assumed ??

And do you have classes for thermal radiation and VCE calculations?

Can you pull up information of the calculation for the video: CVE 351 - Class 34 (Atmospheric Dispersion and Gaussian Model) 30 Nov 2015?

Thank you

Where is the board

textbook?

Please share the PPT

Water flows at rate of 34⅓ through a horizontal ∅150 doctive iron pipe. Determine the head loss in 400m of pipe using the hazen Williams formula.

Dear Isaac, Thanks for the best Course and your good effort to spread the knowledge all over the world, God Bless your Effort, further please can I get the Excel sheet please, I'm not able to get it through the web

Thanks for a clear and effective lecture on this topic，How can i get the pdf version of your Handouts

Thank you very much for this wonderful effort. I have benefited a lot from this lesson. Sincere greetings from Algeria.

That's not the way to calculate D, D is a Capex vs Opex competition. In the practice is way more simple: Keep velocity in between 1~6 m/s for liquids, clean liquids 1~3, slurries or suspensions 3~6 m/s. On Gases is 10~30 m/s. Decision on taking the average, close to min or Max, has to take care of other considerations, like sanding , max conditions, revamps, etc.

Student from a different uni. Thanks for a clear and effective lecture on this topic

Nice video, can you recommend where obteining the pond criterias?

Dear Professor, I`m learning with your excellent lessons the method. Just one question, is it possible to use Hardy Cross also when the flow rate outlets are unknwon. So if I want to use this method for design of fire hydrants system, by imagine that a certain number of hydrants are always fully open?

Do you know the formula for traveltime in a phreatic aquifer with ambiant groundflow and a well with a constant discharge rate?

terima kasih bang,,,

Thank you professor. Many greetings from Polytechnic University of Milan.
