##### 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

ft^{3}/lb, and SI units are usually m^{3}/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:**

V_{t} = V_{0} [1 + A(t) + B(t)^{2}] | ||

where: | ||

V_{t} = volume at t°CV _{0} = volume at 0°CA = 0.5758 ^{-3}B = –0.432 ^{-6} | ||

Solving: |
