Flow TestI 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 1Ran 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 2Exact same setup as Test 1 only with nozzles removed.
This configuration resulted in 700-725gph.
Test 3I took of the 1" tee from the previous tests and ran a 1" 45, 1" 90, then short bit of pipe
This configuration resulted in 925-950gph.
Test 4See picture for configuration.
This configuration resulted in 950-1050gph
Test 5See picture for configuration.
This configuration resulted in 1050-1075gph
