Buoyancy

Buoyancy, abbreviated as B, is when a liquid applies upward force on an object that is completely submerged or floating.

Buoyancy formula

(Eq. 1)  \(\large{ B =  p\; A }\)

(Eq. 2)  \(\large{ B =  \rho \;V \;g }\)

(Eq. 3)  \(\large{ B =  \rho \;g \;h \;A }\)

Where:

\(\large{ B }\) = buoyancy force

\(\large{ V }\) = displaced volume

\(\large{ \rho }\) (Gtrrk symbol rho) = fluid density

\(\large{ g }\) = gravitational acceleration

\(\large{ h }\) = height of liquid displaced by a floating object

\(\large{ p }\) = pressure

\(\large{ A }\) = surface area of object
