The ratio of a liquid's specific weight to that of water is designated as _________________?
Show answer Hide answer
Answer: D. Specific gravity of liquid
Explanation
The specific gravity of a liquid is defined as the ratio of its specific weight to that of pure water. This dimensionless value compares the density of any given substance against the standard reference density of water. It allows engineers and scientists to characterize fluid properties without being dependent on measurement unit systems. Specific weight represents the gravitational force per unit volume of a fluid substance. Pure water serves as the universal baseline fluid standard with a specific gravity value exactly equal to one. Temperature and pressure affect fluid density, so specific gravity measurements are referenced to standard conditions.
Density of liquid describes the mass per unit volume rather than a comparative ratio against water. Density of water is simply the reference denominator used in calculating specific gravity values. Specific gravity of water is always equal to one and does not represent the ratio for other liquids.
