Understand Demand Dependent Analysis (DDA) and Pressure Dependent Analysis (PDA) in EPANET Software

[@mi-marvel6273]

As a Water Engineer, this is the best channel I've come across. I have been looking forward to a channel that will help me understand practical hydraulics and here is one. Thank you Sir

Great to hear! You are welcome!

Been eagerly waiting for this educative and informative tutorials. Thanks Eng. Tom

[@HydroinformaticsAcademy]

Thank you bro!! Lets keep on learning!!🙏

interesting! thank for the video i think epanet show you that flow because you have a emitter exponent in your juntions ( in your PDA Analysis) if you modify the exponent the flow will changed. the PDA analysis is like a Gravity flow (the flow depends on the pressure and the exponent of the emitter.) the DDA analysis is like a pressure flow ( similar a pressure system whit a pump) if you not indicated a pump and curve patterm in epanet! epanet show you negative pressure in your juntions ) that indicates that you need pressure on the water source)

Thank you Marcos! That was helpful..🙏

Bat ,What is the differents between analys DDA and analys PDA?????

[@HydroinformaticsAcademy]

Please rewatch🙏

Thanks for the tutorials, how do you print a pipe layout PDF or other format in epanet .

[@HydroinformaticsAcademy]

I have not covered that but I have another tutorial that explains how to prepare layouts with Google earth and qgis. Link: kzbin.info/www/bejne/jnvWkmuGmaqLi5I I plan to prepare another tutorial on this topic either by using qgis or epanet... so stick around so as you dont miss! Thanks!

@@HydroinformaticsAcademy I think epanet would be better. Thanks

[@HydroinformaticsAcademy]

Sure thing, thank you🙏

Your training is so superb. How I wish you had it in a sequential form-from the beginning to the end for a lame man.

[@HydroinformaticsAcademy]

@@emmanueladewumi8651 Thank you! You mean EPANET tutorial in step by step form for beginers?

[@emmanueladewumi8651]

@@HydroinformaticsAcademy Yes. If you have a proposed development, strip or general survey, maintain 600 or 800mm cover, calculate the volume of earthwork, tie-in to an existing system. How do you go about it? Does Epanet give the setting out data after the analysis? I reiterate, your training is so good!!!!

Hi Lodrick, your explanation is so good. We are a startup looking forward to benefit students in India with your expertise. Please check email from Fresher2Pro. Thank you

[@HydroinformaticsAcademy]

Thank you! Okey I will check soon!
