Point of free discharge
Point of free discharge
(OP)
I have a a scenario where I have to pump up 30m vertically from a datum level to get over a building. The pipe is then ran back to ground level where it discharges atmospherically into an open pit. The discharge point is pretty much at the datum level.
My understanding of static discharge head is that it is the difference between the pump centreline and the point of free discharge.
Where do I assume the point of free discharge is?
Brief details are
The pump will be used intermitently
When the pump is not running the line will be self draining both ways.
The pipe is a fixed diameter

If you provide flowrates and pipe dimensions I can comment more specifically.
