optimal hose size for 1500gph

[psidriven]

i have a jebao dcp-10000 which tops out at 2500gph, but aiming for 1500-2000gph. this site suggests 1in is optimal for 1500gph. is this accurate? any better sites?

It’s the bends that kill the flow. I’ve run across spec flow sheets before that do the math calculations for you. But of course I can’t find them on line now that I’m looking for them.

Will going too big on hose size also kill flow and be less efficient?

Yes. It’s like blowing through a fire hose. The opposite is blowing through a straw. Both are not good. Both will work but not optimal.

It won't kill flow per-say. The same amount of water will go into the pipe, it will will eventually run at a slower velocity. That can allow things to build up and eventually clog. That said, in our applications as an example, I don't think picking 1.25" vs 1" is going to make that much as long as you don't pair it with a severely underpowered pump, like a 200 gph or run the flow really low of a stronger pump.
