WebThe flow index is the slope of the flow curve obtained when results from the percussion cup method or the cone penetration method are graphed. Analysis of test data pertaining to soils of widely varying plasticity characteristics and geological origin indicates that there is an excellent correlation between the plasticity index and the flow ... Webwhere τ is the shear stress, K is the consistency index, γ ˙ is the shear rate, and n is the flow behaviour index.The parameters K and n characterise the rheology of power-law fluids. The flow behaviour index n is dimensionless; the dimensions of K, L −1 MT n−2, depend on n.As indicated in Figure 7.8, for pseudoplastic fluids n<1. When n>1, the fluid is dilatant …
