Dry unit weight


n fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. Specific weight can be used as a characteristic property of a fluid. Specific weight is often used as a property of soil to solve earthwork problems. (Soil is the mixture of minerals, organic matter, gases, liquids, and the myriad of organisms that together support plant life. ) In soil mechanics, specific weight may refer to: The “ dry unit weight” of a soil when all void spaces of the soil are completely filled with air, with no water.
