Then they lay the pipes and surround the pipes with sand and again verify their compression value. Finally...

    Expansion Tank - 25% Ethylene Glycol

    Hi, I just joined the boards today, and am a recent graduate for mechanical engineering. I am designing an expansion tank for a chilled water loop, and it asks for the expansion coefficient for ethylene glycol. I cannot find a ethylene glycol expansion table anywhere. were going from 21F to...
