We have to provide positive inlet pressure to the irrigation tube between 25 & 35 psi. There is a direct relationship between inlet pressure and maximum length of irrigation tube lineal runs. We also have to get the flush water back to the irrigation tank.
The question would be this at the very basic:
Is there a static head in this nearly closed loop system since we pump down the hill and back up it to the same location because the orifices are in the system. Some in our office say it has a static head of 125'.
Or would it be?
In this closed...
The 100 GPM (approx) is derived from a Excel spreadsheet the irrigation tubing manufacturer provides for calculation of proper dose flowrate.
In this case the 1/2" tubing is spread across a supply header manifold that is about 115' wide with a irrigation tube every 5' along that length. The...
I feel that the static head is basically waterlevel to waterlevel in this case and it would vary from pump centerline to discharge point or return point since they would almost be the same.
However, the dissenters from this position are hedging that the orifices create an open point in the...
Want to know everyone's thoughts on this application.
Pumping from a vented to atmosphere wastewater effluent tank downhill through an irrigation network.
The irrigation pipe is small diameter PE pipe (about 1/2") with pressure compensating discharge orifices. These orifices emit a maximum...
