n: the property by which a fluid in motion offers resistance to shear and flow. Usually expressed as newton seconds/metre.

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.

n: ten times the newton, which is the unit of force in the metric system.

n: a dilatant. or inverted plastic, fluid is usually made up of a high concentration of well-dispersed solids that exhibits a nonlinear consistency curve passing through the origin. The apparent viscosity increases instantaneously with increasing rate of shear. The yield point, as determined by conventional calculations from the direct-indicating viscometer readings, is negative;however, the true yield point is zero.

n: This fluid is one of non-Newtonian flow patterns whose unique feature
is that once the fluid is subjected to force,it will start flowing without any gel strength.




a well dispersed, high solids content liquid that has very high apparent viscosity with any applied shear.

n: in fluid dynamics, the state of a fluid in motion is determined by the type of fluid (e.g., Newtonian, plastic, pseudoplastic, dilatant);properties of the fluid such as viscosity and density;geometry of the system;the velocity. Thus, under a given set of conditions and fluid properties, the fluid flow can be described as plug flow, laminar (called also Newtonian, streamline, parallel, or viscous) flow, or turbulent flow.

n: the state of fluid dynamics of a fluid in motion is determined by the type of fluid (e.g, newtonian,plastic pseudoplastic, dilatant),the properties of the fluid such as viscosity and density, the geometry of the system and the velocity,thus under a given

n: a naturally occurring hydrophilic polysaccharide derived from the seed of the guar plant. The gum is chemically classified as a galactomannan. Guar gum slurries made up in clear fresh or brine water possess pseudoplastic flow properties.

n: A hydrophilic polysaccharide from the seed of the guar plant. It is a galactomannan type of saccharide that is highly dispersible into water and brines of various types and salinity. Its water solutions are non-Newtonian and also can be cross-linked by bo

n: (J) the unit used to measure heat, work, and energy in the metric system. It is the amount of energy required to move an object of I kilogram mass to a height of I metre. Also called a newton-metre.

n: a unit of weight or force equal to 1,000 pounds (4,448 newtons).

n: the metric unit of service given by a hoisting line in moving 1,000 newtons of load over a distance of 1,000 metres.

sym: newton.

power law component. As n decreases from 1, the fluid becomes more shear thinning. Reducing n produces more non-Newtonian behavior.
