Buoyancy
Buoyancy 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
