Total head calculation

[RonL1]

Even though I just replaced my submersible pump, I wouldlike to know my head and from what I see online it's a bit confusing.
If I'm running a high of 60 psi through 1 inch pipes, with 4 elbows. Pump is 40 feet down. Static water level is 24 feet down. 55 feet of level pipe from well head to pressure tank.
Thanks for the help.

60 PSI is the same as 138' of head. Add the 24' lift from the water level and you get 162' of Total Head. You can add in some friction loss for the pipe and fittings. But you need to know the flow rate, size, length, and class of the pipe and fittings. For example 10 GPM through 100' of sch 40 PVC will have about 2 PSI or add 4'-5' of head to make the Total Dynamic Head or TDH 167'.

Great ! Thank you. Now if I could find a flow curve chart for this pump. Doesn't seem to be online countryline 1/2 hp 10 gpm 230v. 2 wire

Any 1/2HP, 10 GPM curve will be almost exactly the same. Here is one for Goulds.

Thanks, at my head and pressure, I shouldbe getting maybe a tad under 10.

Should be looking at the 10GS05 which will be about 11 GPM at 167'.

I would if I hadn't just put the new pump down the hole. It forced my hand. But I should have known it was comming as it acted a bit funny a couple months ago... where it ran a 1/2 amps for about 10minutes, then reverted back. Thought it was a loose wire ... should have just ordered back then... but was actually hoping to make it to fall when Temps would be lower. Instead of doing it in 95 degrees. But isn't that how it always works ?

Do you now have the information that you were looking for?

I meant just look at the curve for the Goulds as it should be the same for any 1/2HP, 10 gpm pump.

Tractor supply for a cla200 pump 115vac lists GPH at a certain foot and a downloadable install manual that is detailed lists amps and service factor amps for both 115 & 230 vac.

The head equivalent of 60 PSI is 138'. Total Head is calculated by multiplying the 24' lift from the water's surface by 162'. The pipe and fittings might have extra friction loss added. The size, length, and type of the pipe and fittings, however, must be known. As an illustration, 10 GPM through 100' of sch 40 PVC will have around 2 PSI or add 4–5' of head to create the Total Dynamic Head or TDH 167'.

I think your Math is wrong ADD 24 to 162 dont multiply .

I think your Math is wrong ADD 24 to 162 dont multiply .

or perhaps add the 24 to 138 and you have the 162.
