The specific weight of a fluid, designated by the Greek symbol (gamma), is defined as its weight per unit volume. Thus, specific weight is related to density through the equation. γ = ρg Where; g is the local acceleration of gravity. Just as density is used to characterize the mass of a fluid system, the specific weight is used to ...
14.1 Fluids, Density, and Pressure. A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a substance or object, defined as \(\rho = \frac{m}{V}\). The SI unit of density is kg/m 3.
Molecular weights can be used to calculate Specific Gravity if the densities of the gas and the air are evaluated at the same pressure and temperature.
Specific weight The specific weight of a fluid is its weight, 9 L I C, per unit volume. Density and specific weight are related by gravity: Û L é C l 0 I 7 p Specific gravity Specific gravity is the ratio of a fluid density to a standard reference fluid, typically water at 4˚C (for liquids) and air (for gases):
Do it yourself: Determine the units for density, specific weight, and temperature for the equations above. Determine the percent error for these equations (by comparing results to tabulated values)
Specific weight has units of weight per unit volume, so its value depends on acceleration under gravity or “g.” The units of specific weight are N/m (i.e., N m ) in the SI system or lb/ft (i.e., lb ft ) the USC system.
