Drilling Fluid

Funnel Viscosity
Viscosity is the measure of internal resistance of a fluid to flow; the greater the resistance, the higher the
viscosity. Viscosity of drilling fluids must be controlled.
To determine viscosity, you will need a Marsh funnel (p/n 259-267) and a measuring cup, available from
your Ditch Witch
®
dealer.
1.
Using wash hose and a clean container, take a fresh
sample of drilling fluid. The sample must be at least
1.5 qt (1.4 L).
2.
With finger over bottom of funnel, fill with fluid from
the container through the screen until fluid reaches
the bottom of the screen.
3.
Move funnel over 1 qt (.95 L) container.
4.
Remove finger from bottom of funnel and use the
stopwatch to count the number of seconds it takes for
1 qt (.95 L) of fluid to pass through the funnel. The
number of seconds is the viscosity.
5.
Thoroughly rinse measuring cup and Marsh funnel.
IMPORTANT:
Make sure Marsh funnel is clean and free of obstruction and that you have a stopwatch
available for timing the viscosity.
