P_YIELD_POINT (PTY_YIELD_POINT)

(DDL)

The resistance to initial fluid flow, i.e., the stress required to start fluid movement. This resistance is due to electrical charges located on or near the surfaces of the fluid particles. Typically this is derived from observations made whilst shearing fluid and extrapolating back to zero shear rate. If shear stress measurements have been taken using a Fann viscometer then the YP is taken as 2 x 300 rpm reading - 600 rpm reading. This defines the YP in units of lbf/100 sq ft. For a Newtonian fluid the YP would be zero.
