ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm (0.079–0.248 in) for fine and 20–63 mm (0.79–2.48 in) for coarse. One cubic metre of gravel typically weighs about 1,800 kg (4,000 lb), or one cubic yard weighs about 3,000 lb (1,400 kg). Gravel is an important commercial product, with a number of applications.
The term, yard derives from the Old English gerd, gyrd etc., which was used for branches, staves and measuring rods. [5] It is first attested in the late 7th century laws of Ine of Wessex, [6] where the "yard of land" mentioned [6] is the yardland, an old English unit of tax assessment equal to 1 ⁄ 4 hide.
In Scotland, the peck was used as a dry measure until the introduction of imperial units as a result of the Weights and Measures Act 1824.The peck was equal to about 9 litres (1.98 Imp gal) (in the case of certain crops, such as wheat, peas, beans and meal) and about 13 litres (2.86 Imp gal) (in the case of barley, oats and malt).
After WWI, demand for excavators increased and in 1924 they reached an agreement to build Marion draglines from 1 to 8 cubic yards capacity. In 1927, they built Type-7 1-yard and Type-460 1.5-yard models. The deal to build Marion machines ended in 1936. R&R began building their own designs with the Type-4120 followed by the 4140 of 3.5 cubic yards.
Wheat at 13.5% moisture by weight: 60 lb [7] (27.2155 kg) Soybeans at 13% moisture by weight: 60 lb [ 10 ] (27.2155 kg) Other specific values are defined (and those definitions may vary within different jurisdictions, including from state to state in the United States) for other grains, oilseeds, fruits, vegetables, coal, hair and many other ...
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
Water and soil are monitored periodically to confirm that no adverse soil or groundwater impacts have occurred, and records of the source and disposition of the remediated soil are maintained. Estimated treatment costs, which include transportation, spreading, amendments, and monitoring, are about $4–5 per cubic yard.
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
