How to create a system curve for recirculation system in Epanet

[CHK07]

I'm trying to use Epanet for calculating headloss. But I'm not getting the idea of the software clearly.
I'm using a pump for recirculating water through the filter for cleaning the pool. Its just a simple system having pool, pump and filter.

Water comes from 2 seperate lines and entering the pump. Then pump pushes the water to the filter and through the filter to the pool again.
Also how can I consider the minor losses ( elbows, tee, losses in filter,etc.) in Epanet?
I just need 10m3/hr flow rate and I'm using 2" pipes. How to put the nodes and base demands?

Simulation of fitting and other minor losses can be easily done by just adding the total equivalent length of pipe loss to your real pipe.

If you have a variable pressure loss with flow, most simulators will allow you define a flow element with a resistance coefficient proportional to flow squared.

Sorry, I don't use EPANET.

--Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

For such a small simple system you should just be able to use standard head loss tables.

But any piping head loss will be small compared to what the max head loss is across your filter.

These types of small pool pumps are pretty robust so don't mind going from high flow low head to lower flow higher head.

Usually only 1-2 hp
