Webbin biomass-water slurry tests, as seen in Figure 2. The viscosity of biomass-water slurries decreased rapidly with increased shear rates of up to 100 s-1 but decreased at a slower rate beyond 100 s-1. The viscosity decreased with an increasing particle size, similar to that observed for the coal-water slurries. Fine particles give rise to their ... The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near th…
