of a liquid
https://doi.org/10.1351/goldbook.A00420
The ratio of stress to rate of @S06037@, calculated from measurements of forces and velocities as though the liquid were Newtonian. If the liquid is actually non-Newtonian, the apparent @V06627@ depends on the type and dimensions of the apparatus used.
