From: Experimental study on the drag reduction performance of sodium alginate in saline solutions

Variation of the drag reduction inhibition rate ε with flow rate Q for sodium alginate solutions at different NaSO₄ mass fractions. (a) Variation of ε at a sodium alginate concentration Cp=750 ppm. (b) Variation of ε at a sodium alginate concentration Cp = 1250 ppm.
