Fig. 5: Ratio of measured and Stokes’ settling velocity for all model particles.
From: Impact of heteroaggregation between microplastics and algae on particle vertical transport
Violin plots of the ratio between the measured velocities from the experimental data and the respective Stokes’ law prediction. The Stokes’ velocity was determined based on the effective density and size of the particles, approximating a circular shape. a, Velocity ratio of individual MPs with density higher than water (PLA, PET) of different size classes. b, Velocity ratio of FWS and PET fragments agglomerates. c, Velocity ratio of FWS, PP agglomerates and PS agglomerates of different size classes. Incorporation of MPs into FWS lead to larger deviations from the Stokes’ model.
