- This is the first lecture of Epanet tutorial series and it covers very basic components of drawing network and highlights the features of epanet modelling software. This video is meant for beginners who have started learning hydraulic modelling from scratch, it is helpful for undergraduate students started working on their project works.

Hello' Sir,
Have encountered a challenge with the soft ware, tried designing a simple project for a small village. On running it , it's displays illegal numeric values for the pipes. How can I be helped
Thanks
Hi, I'm just learning with this software. But I have worked a little bit in WaterGEMS. Now my question is.... Should I draw nodes first in order to join those later with pipes... Or is there any option to create node automatically when I draw the pipe.
And my another doubt is... Is there any option like automatic modelling using some dxf files?
hye sir, why is my epanet links give zero (0) velocity while others links have value?
Thanks
I have a question about factor in table. how do I set a factor in the table. ?.. I don't know about how much the factor is in the table.
Hi sir, i choose meters on map units, what will be the dimension in pipe diameter to be used. thank you.
in millimeters
Is the property for pump same with valve?
what are the values should we input for pump power n etc as its not shown in my layout plan huwaaa
I have demonstrated the pump operation is my video related to valve operation, please check and confirm.
Hey Aniket, Your video is excellent! but the background is too noisy.
Thank you sir, That was the first video that i had ever made just with my laptop. I am planning to continue this work with improved video quality and content.
How about the sub-titles, as the volume is extremely LOW despite my vPC volume if fully up? Additionally, the accents are sometimes not easy to decipher!
Thanks for your valuable feedback sir.
I will keep this in mind from next tutorial.
Sir in Run now I am getting major negative values what should be done? 🧐
Hey, check if your reservoir is at a higher elevation than other nodes, and check the diameters, roughness values, make sure you have supplied adequate values of demand, If you are using Tank as a supply source then the minimum and maximum tank levels should be appropriate

How we know elevation value of pump or junction and may be other properties? I mean how you know the value of junction which you write after clicking on properties? Pls let me know
The ground elevation is extracted from the contour maps. In this video, I have simply demonstrated the working of EPANET software. For demand values we need to know the total population of the area and then we need to forecast the population for a specific period (say 30 years etc.). Identify the per capita demand based on the area (rural or urban) to get the base demand of the area, consider adding losses in it (say 15-20%) and you will get the total demand (base demand + losses). Just to simplify the design distribute the total demand equally among all the nodes. However, there are different methods of distributing the demand in the network as well, you can search them. For roughness, you need to identify which type of pipe you are going to use in the distribution network (ductile iron or PE pipes) and also you have to fix the head loss formula (Hazen-William's or Darcy-Weisbach) accordingly you will have to give roughness values as inputs. I hope this answers your question.
How to make print of the executed network,
Well taking the print of the executed network will not work. You need to save the full report generated in the form of text file. Kindly check the toolbar after running the analysis, you will get an option of report. The report will give you all the details of hydraulic analysis
Hey mate can you help me with the water quality analysis
Yes, we can solve your problem,.please share your query

hello sir, may i know the unit used for the elevation ? ft or meter ?
Meters.
How to fill valve elevation
Valves are treated as "links" in EPANET software and there is no option of assigning elevation to any type of link i.e. pipe and valves. Elevation can only be provided to the elements with nodal characteristics such as demand nodes, tanks, reservoir. Thanks
minimum velocity 0.75 l/s, maximum 2.4 l/s
How to save epanet network we draw manually. As I am not able to save it.
Its easy, just select 'File' present at the top line and select ' Save as' option, give a suitable name to your file and its done. Check the location where it is getting stored.
@@waterdistributionsystems8194 Dear Sir it's not saving this way. I m not able to understand what is the problem.
I just tried again, it was *.net. I removed * then typed name it worked.
Sir how ESR is connected with network and what data and as per what calculation we fill it. I have drawn network but not able connect ESR. On run it's showing at all nodes disconnected at 0:00:00 hrs🧐😒😫
@@Shishir-Veer It is because you have not drawn the links properly from ESR to nodes. While drawing the network, make sure you have sufficiently "zoomed in" the two nodes which you want to connect. It generally happens when you are a beginner. Practice it more. Good luck
hi,..i found the videos very helpful..could you provide a certification course inn EPANET ..i would like to have a certified training in EPANET..pls provide your email id
