Buoyant Force Formula:
| From: | To: |
Buoyant Force is the upward force exerted by any fluid upon a body placed in it. It is equal to the weight of the fluid displaced by the body, according to Archimedes' principle.
The calculator uses the Buoyant Force formula:
Where:
Explanation: The specific weight of a body is the ratio of its weight to its volume, and when multiplied by the volume, it gives the buoyant force acting on the submerged body.
Details: Calculating buoyant force is crucial for designing ships, submarines, and other floating structures. It helps determine whether an object will float or sink in a fluid and is essential in fluid mechanics and hydrodynamics.
Tips: Enter specific weight in N/m³ and volume in m³. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between specific weight and density?
A: Specific weight is weight per unit volume (N/m³), while density is mass per unit volume (kg/m³). Specific weight = density × gravitational acceleration.
Q2: Does buoyant force depend on the depth of immersion?
A: For a completely submerged body, buoyant force remains constant regardless of depth, as long as the fluid density remains constant.
Q3: What happens if buoyant force is greater than weight?
A: If buoyant force exceeds the weight of the object, the object will float and rise to the surface of the fluid.
Q4: Can this formula be used for partially submerged objects?
A: This formula calculates buoyant force for entirely submerged bodies. For partially submerged objects, the calculation involves the volume of the submerged portion only.
Q5: How does temperature affect buoyant force?
A: Temperature affects fluid density, which in turn affects specific weight and buoyant force. Warmer fluids typically have lower density, resulting in slightly less buoyant force.
