![]() ![]() The weight is typically calculated in units of force, such as pounds (lb) or newtons (N), depending on the unit system being used. The formula for calculating the weight of a liquid is: To calculate the weight of a liquid, you need to know the volume of the liquid and its density. How do you calculate the weight of a liquid? The submerged unit weight is used in various geotechnical and hydraulic engineering calculations, such as determining the effective stress in soil, calculating the buoyant force on submerged structures, or analyzing stability and settlement of submerged materials. Additionally, the values of γ and γw should be consistent in terms of units for accurate calculation. It’s important to note that the unit weight is typically expressed in force per unit volume, such as pounds per cubic foot (lb/ft³) or kilograms per cubic meter (kg/m³). The submerged unit weight represents the effective weight of the material when it is submerged in water. In this formula, the unit weight of water (γw) is subtracted from the bulk unit weight (γ) to obtain the submerged unit weight (γ’). Where: γ’ is the submerged unit weight of the soil or material, γ is the bulk unit weight (or total unit weight) of the soil or material, γw is the unit weight of water. The submerged unit weight formula calculates the effective weight of a soil or material when submerged in water. In summary, the weight of a floating object in water can be considered zero or very close to zero since it is effectively balanced by the buoyant force. Therefore, for a floating object, the weight of the water it displaces (equal to its volume times the density of water) is equal to its own weight. This buoyant force is equal to the weight of the water displaced by the object.Īccording to Archimedes’ principle, an object will float if the buoyant force acting on it is equal to or greater than its weight. When an object floats in water, it experiences an upward buoyant force that counteracts the force of gravity. The weight of a floating object in water is effectively zero or negligible. What is the weight of a floating object in water?
