Buoyant Force Formula:
| From: | To: |
The buoyant force formula (F_b = ρ × V × g) calculates the upward force exerted on an object submerged in a fluid. This principle is known as Archimedes' principle, which states that the buoyant force equals the weight of the fluid displaced by the object.
The calculator uses the buoyant force formula:
Where:
Explanation: The formula calculates the upward force that opposes the weight of an object immersed in fluid. The buoyant force depends on the density of the fluid, the volume of fluid displaced, and the gravitational acceleration.
Details: Calculating buoyant force is essential for designing ships, submarines, and other marine vessels. It's also crucial in understanding why objects float or sink and is applied in various engineering fields including naval architecture and fluid mechanics.
Tips: Enter fluid density in kg/m³, submerged volume in m³, and gravitational acceleration in m/s². Standard gravity is 9.81 m/s². All values must be positive numbers.
Q1: What is Archimedes' principle?
A: Archimedes' principle states that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.
Q2: How does object density affect buoyancy?
A: If an object's density is less than the fluid's density, it will float. If it's greater, it will sink. If equal, it will remain suspended.
Q3: Does shape affect buoyant force?
A: No, the buoyant force depends only on the volume of fluid displaced, not on the shape of the object.
Q4: What's the difference between buoyant force and weight?
A: Weight is the downward force due to gravity, while buoyant force is the upward force exerted by the fluid. An object floats when buoyant force equals its weight.
Q5: How is this applied in real-world scenarios?
A: Buoyancy principles are used in ship design, submarine operations, hot air balloons, hydrometers, and many other applications where fluid displacement is involved.
