Glycol/Water Mixture

Glycol/Water Mixture

Glycol/Water Mixture

(OP)
Does anyone know of an equation which correlates the density of a water- glycol mixture to a percentage of mix....?

RE: Glycol/Water Mixture

I don't have an equation (assuming you mean at 60F or some basis since that's otherwise another effect on the density).  DOW has this information on glycol mixtures, you could curve fit it on Excel in no time.

RE: Glycol/Water Mixture

(OP)
TD2K,

wher does one find this equation etc?

John

RE: Glycol/Water Mixture

x = fraction glycol

rho mix = x.rho glycol + (1-x)rho water

this should be close enough

RE: Glycol/Water Mixture

John, give me an email address and I'll send you the glycol property package I have.

RE: Glycol/Water Mixture

oh, somebody giving away property data for free? i only have access to yaws' book, which doesn't include mixtures... may I ask to get these data also? Email adress would be: cereal313@yahoo.com

RE: Glycol/Water Mixture

It's in the mail, email that is.

RE: Glycol/Water Mixture

(OP)
I need an equation that correlates the two of them.  If I know the density, I want to plug this value in a equation for an inline deisnity meter to let me know the concentration
