Need a Person that can Figure Flow amounts

[forcrz6]

So I was able to get the Pipping layed last night (Wait that did not come out right). But now this is the question is this.
I have a Piece of PVC coming up from the Mag 12. and at the top of the tank I have it Tee'ed off to go to two bars that will deliver the water back in to the tank. What I need to know is this
How Big, and How many holes should I drill to get the full flow from the pump in these PVC bars?
The PVC size is 1"ID
The bars are both 24" long
Total length traveled upwards by the water from the pump is 4.5 feet
Per my chart that came with the Mag12 we are looking at 1100Gph
I am trying to create a frontal downward flow to the front of the tank with the bar.
Any Ideas?

Here are the calculations i came up with for you design.This is with your 2 horizontal bars being open ended w/out being caped and w/out holes being drilled in the horizontal pipe.I added 2 -45 degree fittings assuming you are using hard pipe and are unable to get a straight shot from the sump to the DT.Total losses are 7.05 feet of head pressure, or 3.05 PSI. with a flow rate of 871 GPH.
I cant only assume logically with limited expertise in this equation the GPH number decreasing with caped off pipes and hole being drilled.
The only way to know for sure is to add a inline flow meter or get a different opinion from someone with more knowledge.
You can verify theses numbers by Googleing "head loss calculator"
*Correction* I forgot the 2-90's to get over the back of the DT.
"Total losses are 7.38 feet of head pressure, or 3.19 PSI. with a flow rate of 843 GPH"
________________________________________________________________
If you where to use 1.5" pipe. Total losses are 5.18 feet of head pressure, or 2.24 PSI. with a flow rate of 1015 GPH

Wow thanks.
The total length w/ bends is 10" But only 4 feet are moving upwards.
Well The calculations That I had and What I got from draining the 30g tank with my mag 12 I was getting 1123.89GPH with the ends uncapped.
So I know that I am getting 1100GPH
Knowing that I am capping off then ends of the Pipes.
I'm thinking I would need 46 Holes at 15/64 or 1/4 to encompass the flow and not loose any flow through the holes.
Can anyone verify that 46 15/64" or 1/4" holes would allow the full 1100GPH to flow freely?

I just tried that Link you gave me. That calculation seem to be way off. for the head flow. The #s I entered and the #s that I am getting conflict with real life testing. HRM.
I just don't know now.
That calculator is comming back with
Total losses are 6.96 feet of head pressure, or 3.01 PSI. with a flow rate of 879 GPH.
But Like I said the calculations from draining out my 30g tank is 1123.89GPH

I guess the best way to test would be either
1. buy and install flow meter.
or
2. put it together and see how your results turn out using the same test method you have already done. You could probably do it with your piping dry fitted.

True. Or just go with the old Hail Mary and hope and prey. I just hope that the in matches the out or I am going to have to put a reduction on the in.

Negative..... Never restrict the intake side of a pump,unless you want to kill it.Just hook her up and let her fly,the flow will be what its gonna be.

Oh No no no. Heh.
I mean I will slow the amount of water coming in from the overflow. if I need to match the Pump.
Not the in on the pump.

I lke the bucket method. fill a 5 gallon bucket...count the seconds.then 5 divided by the seconds. then multiply by 60 then times 60 again. theres your GPH.

Yea But I am not tring to Figure the Flow from the Pump. I know that.
I am trying to figure out the size that 46 holes have to be. allow 1100gph to flow freely.
