7/16" ID or 1/2" ID? - Page 2

7/16" 76%
He said it would have 24% less flow not the capacity of the tubing...I don't think anyone is concerned with the capacity of tubing when its used for WC'ing..

Now, I've been told the increase in flow is not worth the turbulence caused at the join with the fittings.

It's tough to say what is a better choice, but I believe they are more or less the same..

Maybe capacity wasn't the best word, but in the case of a conduit such as tubing, it has a direct bearing on flowrate, especially with a non-compressible substance such as water

Your bottlenecked by the smallest ID in the loop I don't care if you had a 1" ID tube and it had to go trough a 7/16" ID fitting your flow would be reduced to what can pass through the 7/16" ID...

Hmmmm... ira-k, I know you have some 1/2" and 7/16" lying around. Care to run a vertical tube test for head and a bucketfilling test for flowrate?
Once again...

With out fittings in it of course the 1/2" will flow more...But when you put it in a loop with 7/16" ID fittings it will be reduced to 7/16" flow rate...

Low and behold its already here, and with UPS ground and all I have to say is dannnggg. Beats other watercooling shops and a week for delivery. By the way this was purchase from Petra's Tech Shop.

Anyways 7/16" sure looks more restrictive but I will give it a shot, at the worst I can order some 1/2" and expect it the next day yay!

Hey that was fast...They are a good shop...If you do change it out to 1/2" do it in the same lengths and see if it cools any better..

That's the plan, might do a little article although might need some external help from someone to make sure I measure things correctly.

Using that logic, you wouldn't need tubing any larger than the most restrictive part of the loop.

The fittings add restriction to the loop, but dropping your entire loop to 7/16" would increase the restriction much more.
