Which outcome occurs when injected polymer concentrations decrease along a pipeline?

💡 Explanation

Decreasing polymer concentration lowers 'dynamic viscosity' which then cuts drag reduction, because drag reduction relies on increased viscous stress at the edge of a fluid volume. Therefore drag reduction declines rather than turbulence increasing because polymers enhance laminar structures.
