n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

n: the unit of force in the centimetregram- second system of units, equal to the force that gives an acceleration of 2 centimetres/ second squared to a 1 gram mass.

n: an absolute flow property indicating the flow resistance of certain types of fluids. It is a measure of shearing stress.

n: a measure of internal resistance of fluid attributable to the amount,type and size of solids present in a given fluid. It is expressed as the number of dynes per sq cm of tangential shearing force in excess of the bingham yield value that will induce a un

an absolute flow property indicating the flow resistance of certain types of fluids. A measurement of shear stress.

n: the viscosity of a liquid in which a force of 1 dyne (a unit of measurement of small amounts of force) exerted tangentially on a surface of 1 square centimebe of either of two parallel planes 1 centimetre apart will move one plane at the rate of 1 centimetre per second in reference to the other plane, with the space between the two planes filled with the liquid.
