Archimedes Principle

buoyancy 4Archimedes principle is the upward bouyancy force that is extended on a body that is completely or partially immersed in a fluid and is equal to the weight of the fluid that the body displaces.

 

Archimedes's principle formula

\(\large{ B = \rho \; g \; V  }\)   

Where:

 Units English Metric
\(\large{ B }\) = buoyancy \(\large{lbf}\) \(\large{N}\)
\(\large{ \rho }\)  (Greek symbol rho) = density of fluid \(\large{\frac{lbm}{ft^3}}\) \(\large{\frac{kg}{m^3}}\)
\(\large{ g }\) = gravitational constant \(\large{\frac{lbf-ft^2}{lbm^2}}\)  \(\large{\frac{N -m^2}{kg^2}}\)
\(\large{ V }\) = volume of solid \(ft^3\) \(m^3\)
