Archimedes law is the primary law of buoyancy
The weight of the displaced fluid is directly proportional to the volume of the displaced fluid.
Among submerged objects with equal mass, the objects with the greater volume will have greater buoyancy
As a fluid’s velocity increases, the pressure it exerts decreases (and vice versa).
A common application is a Venturi tube, which narrows at one point; the pressure decreases, and velocity increases.
P1 + ½ pv12 + pgh1 = P2 + ½ pv 22 + pgh 2
Pascal's Law Archimedes was put in charge of discovering if a goldsmith was secretly replacing the gold in the king’s crown with silver. Archimedes, in the middle of taking a bath, found that when he put his foot in the bathtub, some water rose and poured out of the tub. With this, he placed the king’s crown in water with a gold crown of equal weight. The king’s crown caused more water to overflow, and Archimedes therefore concluded that since it had more volume for the same weight, (gold is more dense than silver), the king’s crown contained silver. The goldsmith was executed.
Law discovered by:
At a constant pressure the volume of a gas is directly proportional to its temperature. V/ T=k
As temperature increases volume increases.
Charles came up with the idea to test it when he was in a hot air balloon which is a use of the law.
