![]() ![]() Moist unit weight The unit weight of a soil when void spaces of the soil contain both water and air. Hematite nanostructures are strong candidates for the development of sustainable water splitting technologies. In soil mechanics, specific weight may refer to: Specific weight is often used as a property of soil to solve earthwork problems. The density of water depends on the temperature and pressure. The formula to calculate density is mass of the substance/volume of the substance. The units of density of water are kg/m3, lb/ft3, g/ml or g//cm3. Specific weight can be used as a characteristic property of a fluid. The density of any substance is defined as the ratio of substance mass to its volume. For this reason, units are expressed as force per unit volume (e.g., N/m 3 or lbf/ft 3). In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. When you add salt to the water, its mass will be bigger and then the density will be higher. You may be wondering now why the density of seawater is higher than the density of fresh water. But the density of seawater can range from 1020 to 1029 kg/m3. Pressure may also affect values, depending upon the bulk modulus of the material, but generally, at moderate pressures, has a less significant effect than the other factors. The average seawater density is 1.025 kg/m3. It depends on the value of the gravitational acceleration, which varies with location. Note Temperature must be within the ranges 0-370 C, 32-700 F, 273-645 K and 492-1160 R to get valid values. The output density is given as g/cm 3, kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. Unlike density, specific weight is not a fixed property of a material. The calculator below can be used to calculate the liquid water density at given temperatures. The standard gravity is acceleration due to gravity, usually given in m/s 2, and on Earth usually taken as 9.81 m/s 2. The density of the material is defined as mass per unit volume, typically measured in kg/m 3. ![]()
