viscosities

[LouD]

How is viscosity calculated? I am particularly interested in how it evolves in a gas-H2O system. I did not find any reference to this in either Craig's book or the software documentation. Did I miss something?

Hi Lou:

 

Let me see what I can find out.

Density calculations are given as follows (the equations are taken out of UIUC's Basin modeling program guide):

 

 

I hope that helps.

hi Tom,

 

Thanks, that's interesting (and is indeed useful), but what I was really wondering about was viscosity. Maybe this is also in the Basin2 guide, but that is no longer available at UIUC hydrogeology site, I gather they "retired" the software.

Oops- sloppy. I posted the wrong part of the manual.

 

Viscosity in Basin2 is calculated via either a lookup table or equation- as soon as I figure which one GWB uses, I'll post the correct info here.

hi Tom,

 

OK, cool -and a reference to the method would be great.

Hi Lou:

 

Here is the correct portion of the manual:

 

 

The reference is as follows:

 

Phillips, S.L.H, H. Ozbek, A. Igbene and G. Litton, 1980, Viscosity of NaCl and other solutions up to 350C and 50 MPa pressures. Lawrence Berkely Laboratory Report LBL-11586, 71 p.

 

Let me know if that resolves it for you.

 

Regards,

OK, thanks this is useful.
