Marsh Cone Funnel

This cone is used to find out viscosity of bentinite slurry and like material. The marsh cone is 6 inch in diameter at the top and 11 inch(280mm) long, and tapers to join a tube 2 inch long and 3/16 inch side dia. The capacity of the funnel is 1500 cc. Time in seconds required to flow out 1000 cc of slurry from cone is measured as funnel viscosity of the material.
