The specific weight of water is 9.81 kN/m³ at 4 °C. This value is often used in engineering calculations to determine the weight of water in a given volume.
The specific weight of water can be calculated by dividing the weight of water by its volume. The weight of water can be found by multiplying its density (1,000 kg/m³) by the acceleration due to gravity (9.81 m/s²).
The specific weight of water is important in various engineering and scientific applications. It is used in determining the buoyancy of objects, designing water systems, and calculating the weight of water in hydraulic systems.
Yes, the specific weight of water changes with temperature. At 4 °C, the specific weight of water is 9.81 kN/m³. As the temperature increases, the specific weight decreases, and as the temperature decreases, the specific weight increases.
The specific weight of water is typically measured in kilonewtons per cubic meter (kN/m³). However, it can also be measured in pounds per cubic foot (lb/ft³) or newtons per cubic meter (N/m³).
