Flow Test
I ran a test yesterday and wanted to share my finding with the group. When most of us talk about the head loss on our pumps we talk about pipe, fittings, and equipment. We hardly ever talk about our nozzles and loclines. I searched for information on this and even posted about it without any responses, so I decided to run a test.Prelude:
My system has the Jebao DCP 15000, 4' vertical lift, 5' total pipe (PVC 1"), (1) 45, (2) 90s, & (1) swing check valve for every single test. I wish I had a flow meter to give solid data but ran the test twice for every setup for accounting human error and reaction time. My method was filling the return pump section and running the pump with all water ending in a bucket then converting gallons pumped in that time to gph.Test 1
Ran a 1" tee to dual 1/2" reducers then dual 1/2" locline with nozzles attached on each side.This configuration resulted in 550-600gph.
Test 2
Exact same setup as Test 1 only with nozzles removed.This configuration resulted in 700-725gph.
Test 3
I took of the 1" tee from the previous tests and ran a 1" 45, 1" 90, then short bit of pipeThis configuration resulted in 925-950gph.
Test 4
See picture for configuration.This configuration resulted in 950-1050gph
Test 5
See picture for configuration.This configuration resulted in 1050-1075gph
