| Abstract: | An equation describing the friction of polymer solutions was developed through the studies on the rheology and friction of HPAM solutions of different concentrations and molecular weights of HPAM. HPAM solutions formulated with five different HPAM concentrations and HPAM with four different molecular weights were measured for their steady-state shear viscosity, thixotropy and flow curves. The friction data of the HPAM solutions were calculated by measuring the differential pressures of these solutions in a pipe with inner diameter of 0.77 cm at flow rates ranging between 3 L/min and 9 L/min. The effects of the molecular weight and concentration of the polymer on friction reduction of solution were analyzed. Based on these studies, a friction coefficient equation describing the relationship among the friction coefficient f, the generalized Reynolds number Re and the flow pattern index n of the polymer solutions was established. |
