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

Effect of salt content on the drag reduction inhibition rate of sodium alginate solutions. (a) Variation of the drag reduction inhibition rate at a salt mass fraction of 3% for different sodium alginate concentrations. (b) Variation of the drag reduction inhibition rate at a salt mass fraction of 6% for different sodium alginate concentrations.
