n: a complex, non-Newtonian fluid in which the shear force is not proportional to the shear rate. Most drilling muds are plastic fluids.

n: a complex, non-newtonian fluid in which the shear force is not proportional to the shear rate. A definite pressure is required to start and maintain movement of liquid. Plug flow is the initial type of flow and only occurs in plastic fluids. Most drilling

a complex, non-Newtonian fluid whose shear force is not proportional to the shear rate. Pressure is necessary to start circulation of the static fluid. Main low rate flow is plug flow. Yield point is greater than zero.
