The formula to calculate the float weight (FW) is:
\[ FW = V \times D \times 9.81 \]
Where:
Float weight refers to the weight of an object when it is floating in a fluid. It is calculated based on the object's volume and density, and the acceleration due to gravity (9.81 m/s²).
For example, if the volume of the object (V) is 2 m³ and the density of the object (D) is 500 kg/m³, the float weight (FW) can be calculated as follows:
\[ FW = 2 \times 500 \times 9.81 = 9810 \text{ N} \]
So, the float weight for an object with a volume of 2 m³ and a density of 500 kg/m³ is 9810 N.
