WebThe density of a substance is defined as its mass per unit volume. It is denoted by the Greek letter ρ (rho): ρ = m/V where m is the mass and V is the volume. In some industries, the density is still incorrectly defined as weight per volume (this is … WebAny object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of ...
