Pump/Plumbing question...

[Whatigot]

I won't replumb.
Just put the plumbing in in the first place and the pump I am upgrading from is so far inferior to the quiet one 6000 that I think I'll still come out on top.

Good learning experience in any case just to see.

Just out of curiosity, what IS the math behind that 75% loss Phelps?

Complex iterations to solve for the pipe friction coefficient and then a little bernoulli, but to be honest I can't remember exactly how to do it anymore I just happen to still have the program in my old calculator I think my fluid mechanics days are behind me now, well I hope so anyway.

I also just remembered about the RC head loss calculator, that would have probably been easier.

whoah, you speak klingon?

lol

I appreciate the help Phelps, glad someone on here is smart enough to answer these questions for me.

calc says I'll still have 811 GPH, plenty for me but a huge loss from the 1500 it has at 0 head....
Knew there was a calculator somewhere....

Don't forget about how fast your tank's overflow drain is. I have a quietone 6000 on my tank but had to "T" it off to reduce flow cause my drain bulkhead would never keep up otherwise. Great pump choice IMO, not that I have lots of experience with other pumps but the quietone has been working great on my tank for the last year and a half.

HI How have you piped it? I piped 1" then 1"x3/4"x3/4" tee 3/4" to tank and 3/4" to front of sump it goes through the sump and calerpa doesn't restrict the pump.75% of flow into tank keeps up with return .
