Calculate the pressure first by the getting product of (h x rho x g).Then calculate thrust =pressure x area
Recall pressure and thrust.
Buoyancy or upthrust refers to an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object
Recall high-pressure exertion in a small surface area
A barometer measures air pressure, Altimeter measures altitude, Manometer measures pressure difference, Lactometer used to test milk's purity
Iron nail has lesser density than that of mercury
Fluids exert the same pressure in all directions at the same level. The example satisfies the statement
The Archimedes principle states that upward buoyant force is exerted on a body immersed in a fluid, whether fully or partially, is proportional to the weight of the fluid that the body displaces.
A dam has broader walls at the bottom than at the top. As, the depth increase, the pressure applied by water on the walls of the dam also increases.
The pressure at a point in a liquid depends upon acceleration due to the gravity (g), the density of the liquid (p), and the point below the free surface (h).
