Soil flow index
WebThe flow index may be calculated from the following equation also: Flow Index = I f = W 1−W 2 log10(N2 N1) I f = W 1 - W 2 log 10 N 2 N 1. Where, If is flow index. W1 is moisture … WebPlasticity Index. Plasticity Index (PI or I P) is calculated as the Plastic Limit subtracted from the Liquid Limit and is an important value when classifying soil types.. PI = LL - PL. Shrinkage Limit. The shrinkage limit (SL) is …

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 rather … WebAs the friction coefficient increases the initial plastic zone moves closer to the surface and unconstrained plastic flow occurs at a lower normal ...
