WebFeb 11, 2024 · In the United States, the measuring cup volume of the Marsh funnel is one quart. 9 This measured flow time is referred to as the Marsh funnel viscosity (MFV). Then, the longer the flow time of the fluid, the lower the fluidity, and the higher the MFV. WebApr 13, 2024 · The orifice, or inside of the tube at the bottom of the cone, has an inside diameter of 3/16 inches (4.76 mm). The edge of the funnel walls themselves certainly have additional zones of shear, but these have a lesser effect on a fluid. A fluid in a Marsh funnel only sees significant shear when it passes through the orifice into the cup.
