Variability of Natural Dust Erosion from a Coal Pile
AP-42 lists as ranging from 0.55 m s −1 (at the base of a crushed coal pile) to 1.12 m s −1 (uncrusted pile) giving a factor-of-2 difference in on a coal pile. The former value is a lower limit in estimating wind erosion and is the threshold (along with its wind speed equivalent u t ) referenced later in this paper.Web

Calculating Stockpile Capacity
where: R = stockpile radius in meters A = angle of repose for material to be stockpiled D = density of material in kg/m³. Note that the capacity of the conical stockpile varies with the cube of the radius of the pile. This means that the capacity of the conical pile grows very rapidly as the height (and hence the radius of the pile) increases.Web

Coal | Properties, Formation, Occurrence and Uses
Knowing the physical properties of coal is important in the preparation and use of coal. For example, coal density ranges from about 1.1 to about 1.5 megagrams per cubic metre, or grams per cubic centimeter. Coal is slightly denser than water and significantly less dense than most rocks and mineral matter.Web

Controlling Wood Moisture Content & Why It's Important
Here's why. Wood changes size as its moisture content goes up and down. When wood's moisture content increases, it expands. When it's moisture content decreases, it shrinks. If the wood hasn't reached its EMC prior to being used in a project, it will continue to either expand or shrink after the project is complete.Web
