1,Introduction The Marsh Funnel is a simple device
for indicating viscosity on a routine basis. When used with
a measuring cup the funnel gives an empirical value for the
consistency of a drilling fluid. The number obtained depends
partly on the effective viscosity at the rate of shear prevailing
in the orifice, and partly on the rate of gelation.The Marsh Funnel
Viscometer Model MLN-3 and MLN-4 are made of rugged plastic, Model
MLN-3A and MLN-4A are made of stainless steel that
resists temperature change deformation. The measuring cup,
graduated in cubic centimeters and fluid ounces, is designed
specifically for use with the Marsh funnel. This combination is
used for making rapid, on the spot measurements of drilling fluid
viscosity. The Marsh funnel readings are only general measurements,
but the frequent reporting of the Marsh funnel viscosity will
indicate changes in the fluid viscosity that could require
corrective action.Funnel viscosity is the ratio of the speed of the
sample fluid as it passes through the outlet tube (the shear rate)
to the amount of force (the weight of the fluid) that is causing
the fluid to flow (the shear stress). Marsh funnel viscosity is
reported as the number of seconds required for one quart of sample
fluid to flow out of a full Marsh funnel.In addition to the
Marsh funnel, the viscosity measurement procedure requires
a graduated container (measuring cup) to receive the fluid as
it flows out of the funnel, a means to measure elapsed time
(stopwatch), and a thermometer for measuring the temperature
of the sample.2,Type Specification
