How many gallons of fluid would I need to fill 4800 feet of 3/4 inch tubing for my heating system?

    1.89 gallons per hundred

    feet of 3/4 pex. 48 x 1.89= 90.72 x 40 % glycol = 36.28 gallons. hope this helps.

    Anyone know if there are some good conversion charts for pipe volumes in this site somewhere.??? Would be a handy place for them, and give me another reason to spend time in here, as if I need one. This place makes a nice little diversion to a busy schedule.

    If you have copper pipe w/ id of 3/4" then the 110 gal. figure is what you want.
    If you have 5.30 cubic inches per lf of 3/4" pipe x 4800 lf divided by 231 cubic inches per gal. you get 110 gal's.


    Also the percentage of gylcol mix you need, all depends on the strength of the gylcol you have. 60%? 96%?

    Pipe Chart & PG Volume

    Steve
    I have a chart for pipe size and volume that we publish for
    our FireFighter PG product. Give me a Fax number & I'll send one over.

    The PG question would be better answered over the phone. These questions usually lead to other questions.

    Try

    Siggys "Design Studio" software. You can input boiler capacity, pipe size and length, fittings, and loop diameter and length, etc. It will give you total capacity and glycol %. Then you can size the expansion tank!

    Pipe/tube Volume

    Jeff -
    I'm never without my Grundfos Plumbing/Heating Handbook. My copy is from 1991. It lists inside diameters for copper, brass, plastic, and steel from 1/2" to 4".
    Volume per foot in US gallons = (ID squared)x(pi/4)x 12/231. OK, so you knew that already.

    Excel Spread sheet.

    I wrote an Excel spread sheet that handles tubing up to
    1-1/2" in diameter.

    If you're interested in receiving it, you can send an e-mail to my company address which is mark.eatherton@advancedhydronics.com and I will be glad to send it to you.

    Don't forget to include the e-mail address you want it sent to.
