Funnel viscosity:

Terms Related to Funnel viscosity

• Marsh funnel viscosity

  Commonly called the funnel viscosity. The marsh funnel viscosity is reported as the number of seconds required for a given fluid to flow 1 qt ...

• Seconds api

  A unit of viscosity as measured with a marsh funnel according to api procedure. See api rp 13b, marsh funnel viscosity.

• Marsh funnel

  A calibrated funnel used in field tests to determine the viscosity of drilling mud.

• Apparent viscosity

  1. The viscosity of a fluid measured at a given shear rate at a fixed temperature. In order for a viscosity measurement to be meaningful, ...

• Absolute viscosity

  The measure of a fluid’s ability to resist flow without regards to its density. It is defined as a fluid’s kinematic viscosity multiplied by its density.

• Viscosity

  A measure of the resistance of a fluid to flow. Resistance is brought about by the internal friction resulting from the combined effects of cohesion ...

• Pseudoplastic

  Having the capability of changing apparent viscosity with a change in shear rate. Pseudoplastic fluids gain viscosity when subjected to a decrease in shear rate, ...
