A face cord is an informal measurement for stacked firewood, [1] sometimes called a rick. [2] Width and height is typically the same as a cord (3.6 m 3), but the depth can vary. [3] The front face is the same as a cord 4 by 8 feet (1.2 by 2.4 m), hence the name. The depth is generally 16 inches (410 mm) (for use in residential fireplaces) but ...
A cord of wood. The cord is a unit of measure of dry volume used to measure firewood and pulpwood in the United States and Canada.. A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching, and compact), occupies a volume of 128 cubic feet (3.62 m 3). [1]
If measuring a buried interface, the second (less dense) phase is then added on top of the undisturbed primary (denser) phase in such a way as to not disturb the meniscus. The force at equilibrium can then be used to determine the absolute surface or interfacial tension. Due to a large wetted area of the plate, the measurement is less ...
The Wilhelmy plate tensiometer requires a plate to make contact with the liquid surface. It is widely considered the simplest and most accurate method for surface tension measurement. Due to a large wetted length of the platinum plate, the surface tension reading is typically very stable compared to alternative methods.
One of the useful methods to determine the dynamic surface tension is measuring the "maximum bubble pressure method" or, simply, bubble pressure method. [ 1 ] [ 2 ] Bubble pressure tensiometer produces gas bubbles (ex. air) at constant rate and blows them through a capillary which is submerged in the sample liquid and its radius is already known.
A classical torsion wire-based du Noüy ring tensiometer. The arrow on the left points to the ring itself. The most common correction factors include Zuidema–Waters correction factors (for liquids with low interfacial tension), Huh–Mason correction factors (which cover a wider range than Zuidema–Waters), and Harkins–Jordan correction factors (more precise than Huh–Mason, while still ...
A tension meter is a device used to measure tension in wires, cables, textiles, Mechanical belts and more. Meters commonly use a 3 roller system where the material travels through the rollers causing deflection in the center roller that is connected to an analog indicator or load cell on digital models.

In France, Belgium, and Switzerland, people still use the "cord" to measure wood to be burnt in a fireplace. In other circumstances (i.e. forest surveying), they measure wood in steres. —Preceding unsigned comment added by 75.45.178.123 ( talk ) 06:13, 16 March 2010 (UTC) Also according to John Winter (royalist) the term was used in 1628 in ...
