From Flow Measurement
Some data provide specific volume rather than density. This term is volume/
mass and is merely the reciprocal of density. Tables and graphs for properties of
steam show specific volume of steam rather than density. English system units are
ft3/lb, and SI units are usually m3/kg.
Density can be derived from the volumetric expansion equation. For example:
The density of 100% sulfuric acid at 20°C is 1.8305 kg/liter. What is its
density at 50°C? The equation is found to be:
|Vt = V0 [1 + A(t) + B(t)2]|
|Vt = volume at t°C|
V0 = volume at 0°C
A = 0.5758-3
B = -0.432-6
