Phosphoric Acid (H3PO4) - coefficient of expansion

Phosphoric Acid (H3PO4) - coefficient of expansion

(OP)
Hi,

I'm making some heat transfer calculations, to determine a steam coil to heat a phosphoric acid tank.
For this i need the coefficient of expansion of this acid.

I've searched a lot but i didn't find anything. Does anyone have a value??

Thanks

RE: Phosphoric Acid (H3PO4) - coefficient of expansion

No, but you can calculate/estimate the cubic thermal expansion of the acid using density vs. temperature data, which will be easier to find. The fifth post in thread124-171158: Volume for blocked piping & Thermal RV has the definition of the cubic thermal expansion. I hope this helps.

Good luck,
Latexman

Technically, the glass is always full - 1/2 air and 1/2 water.

Dear Latexman,

Thanks in advance for the reply. Meanwhile, i've already made that.
I've putted this post, but i forgot that this could be obtained exactly as you said.
So thank you anyway.
