What is the specific volume of a liquid measured in?

• A. ft3/lb
• B. m3/kg
• C. kg/m3
• D. lb/ft2

Answer: (A)

The specific volume of a liquid is defined as the volume occupied by a unit mass of the substance. It is typically measured in terms of cubic feet per pound (ft³/lb) or cubic meters per kilogram (m³/kg), reflecting the relationship between volume and mass. Specifically, the correct choice reflects the concept of specific volume in the context of imperial units; thus, expressing specific volume in cubic feet per pound is appropriate when using the imperial system. In contrast, while cubic meters per kilogram does indicate a measurement of specific volume in the metric system, the focus of the question might indicate a preference for imperial units. The other options, including kilograms per cubic meter and pounds per square foot, do not represent specific volume correctly. Kilograms per cubic meter (kg/m³) is a measure of density rather than specific volume, and pounds per square foot (lb/ft²) is a measure of pressure or force area rather than volume. This clarification helps in understanding the proper measurements used for specific volume and distinguishes it from similar concepts like density and pressure.
