plastic viscosity technical , PV (abbreviation)

With an increase in the dosage of SP, both yield stress and plastic viscosity decreased significantly.

Drill string pressure loses higher in fluids higher densities, plastic viscosities and solids.

Used to determine the apparent viscosity, plastic viscosity, yield point, and gel strengths of drilling fluids.

By contrast the Bingham Plastic requires two parameters, the yield stress and the slope of the line, known as the plastic viscosity.

Such modification in the pore-water salinity illustrates how soils can have similar plastic viscosity and similar remolded strength but different yield stresses.

The rheological behavior of some sensitive clays has shown that there are positive relationships between plastic viscosity, yield stress, remolded shear strength, and liquidity index.

The replacement rate of cement by natural zeolite for a constant SP content significantly increased the yield stress and apparent and plastic viscosities, and reduced the fluidity and deformability of the cement-based grouts.

Hands-on-training on measurements of API mud properties: Alkalinity, calcimetry, hardness, solid content, pH, rheology (apparent viscosity, plastic viscosity, gel strength and yield point), water loss and mud density.

The instrument is a rotational-type device powered by means of an electric motor or handcrank, and is used to determine the apparent viscosity, plastic viscosity, yield point, and gel strengths (all of which see) of drilling fluids.
