how much water will drain though a 1 1/2inch hole

how mutch water will flow out of a 1 1/2inch hole on the bottom of my 8x2x2 to the sump? or what size pump do i need for this to work?

 

lol wut? ... hey i live in melbourne too! where do you buy your corals from?

 

hey mate, what i mean is...... i will have a 1 1/2inch hole in on the bottom of my tank with a overflow....i want to know how mutch water will it drain? and what powerhead i will need?


i goto Mentone alot and reef and river in geelong, how about u?

 

I'm pretty sure a 1" hole will drain 1200 gph, so a 1.5" should be around 1800.

thanks

 

Correction....A 1" hole will drain 600 gph. Bigger AGA RR tanks have 2 one inch drains and they can do 1200 GPH because there are 2 overflows......

 

Correct, 1" drain is 600gph, so a 1 1/2" should be 900gph.

Actually, in tubing, going .5 " bigger will yield greater flow than 50% more than a 1".

I bet the flow available through a 1 .5" bulhead is probably around double of the 600gph that a 1" can do.

I used to work at a Plumbing and Boiler shop. There is a chart available that will tell you flow capabilities of pipe. I don't recall off the top of my head, but we used a lot of 1/2" and 3/4" pipe in residential applications, and going to the 3/4" from the 1/2" would allow you to pretty much do whatever you wanted to do because the increase in size by 1/2 the diameter would yield around 2x the flow, not 1.5x the flow.

 

oops, my bad. I thought it sounded a little high.

you can measure it easily. get a container with known volume, then record the time taken for the container to fill. then u can calculate flow rate. [unit volume/ time]
