T-line vs Reservoir

Chew_Toy · 11-18-2004, 10:25 PM

I was wondering with all the threads I have seen on the subject about which is better if anyone has the pressure drop of both. Like the Bayres from Swiftech and a standard 1/2" T-line setup.

Dont imagine their would be any measurable difference provided the same size fitting is used on either setup. Someone please correct me if I am wrong.

That was my thinking also untill I saw this in PHs article on maximizing flow in a system.

You will also notice that a T connector produces considerable pressure drop even when flow proceeds straight through the T

Yes, but that is not comparing it to a res. If you compare the id of the t to the id of the two bards entering and leaving the res, and their ids are the same, then I would think the amount of resistance would be equal.

That is my guess also but I know that you cant really asume anything and if anywhere there were somenone that had the figures it would be here.

I bet he was referring to the flow drop by the fittings flow restriction + turbulence.

There will be the same fittings flow restriction on a res as well but less turbulence.

I think part of this can be avoided by doing the 'hot water stretch' with your tubing and getting it over fittings with the same ID as the tubing itself. Yep, its a pain but should result in less restriction.

To maximise flow/pressure I dont have a T piece nor a reservoir.
The water pipes are quite long and have fitted a 1/2" hosepipe connector to join 2 sections of pipe together.
To get rid of air, I manouver the air to the connector and then open it, top up the water and refit the pipes. A very small amount of air is left in the system as that cant be helped.
The system ran 4 months before I decided to top it up.

Flow must be good with a Ford Sierra Heatercore (+1x120mm fan), Antarctica Block, driven by only an Eheim 1048 pump, cooling a 2.0V XP-M @ 2.7GHz to 40C load (measured at the CPU die with external sensor), ambient 22C.

I hope to see some figures on flow rates with/without a res as I dont have a flowmeter yet (nor know where to get a worthy one for pennies).
