..., fv = 0. 31. Experimental data indicate this increase is smaller for non-Newtonian fluids such as fracturing gels. The following provides a simple modification of the Newtonian correlations for non-Newtonian fluids with a single phase. For two phase fluids, such as an emulsion of foam, a more...
