WebIn materials science, a Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form. [1] It is used as a common mathematical model of mud flow in drilling engineering, and in the handling of slurries. WebYou can assume a dynamic viscosity for water of 0.00131 kg/m-s and a density of 999.7 kg/m² You should specify the number of sedimentation basins, the basin dimensions, and the basin overflow rate and hydraulic residence time. Sludge scrapers come in a standard 5-meter length, so your basin width should be in increments of 5 meters. theory about indigenous people
