DENSITY AND SPECIFIC GRAVITY
Density is defined as mass per unit volume (Fig. 2–3). That is,Density: (2–1) The reciprocal of density is the specific volume v, which is defined as volumeper unit mass. That is, v ! V/m ! 1/r. For a differential volume elementof mass dm and volume dV, density can be expressed as r ! dm/dV.The density […]
