measured in kilograms per cubic meter kgm 2 Specific Gravity Specific gravity is the ratio of the density of a substance to the density of a reference substance usually water at 4C Its a dimensionless quantity and helps compare the density of different fluids Buoyancy Buoyancy is an upward force exerted by a fluid on an object immersed in it This force is equal to the weight of the fluid displaced by the object as explained by Archimedes Principle Hydrostatic Force The force exerted by a fluid at rest on a submerged object is called hydrostatic force It acts perpendicular to the surface of the object and is proportional to the pressure and area Solving Common Fluid Statics Problems Lets explore some common problems encountered in fluid statics and their solutions Problem 1 Pressure at a
