What unit is used to express the density of liquid R717?

The correct unit to express the density of liquid R717, which is ammonia, is typically in kilograms per cubic meter (kg/m3) or grams per cubic centimeter (g/cm3) in many scientific contexts. Therefore, density is commonly understood as mass per unit volume, and in industrial or engineering scenarios, it can also be expressed in pounds per cubic foot (lbs./ft3).

Using pounds per cubic foot (lbs./ft3) as a unit provides a convenient measure for those operating in environments where the imperial system is standard. This makes it practical for engineers and operators who deal with machinery and equipment in certain industries.

Understanding density is critical in industrial refrigeration as it influences system design, fluid properties, and performance calculations. Thus, pounds per cubic foot is a valid unit for expressing liquid densities like that of R717 in specific applications.
