INVESTIGATION OF THE EFFECT OF TEMPERATURE AND SALINITY OF SOLVENT ON REDUCING THE FRICTIONAL DRAG IN PIPES BY MEANS OF POLYMERIC ADDITIVES

Some reduction in the effectiveness of polymer (polyacrylamide) addition is established experimentally to occur with increasing the solution temperature, and also in the presence of sea-water salts in the solvent. It is noted that with a reduction in temperature the threshold Reynolds number tends to decrease and the relative viscosity of the solution decreases also. An estimate of the effect of temperature and salinity allows the claim that the Toms effect is controllable.
