At -17 degrees, what is the specific volume measured?

To determine the specific volume of a refrigerant at a given temperature, it’s important to understand the principles of thermodynamics and how they apply to refrigeration systems. The specific volume is defined as the volume occupied by a unit mass of a substance, typically expressed in cubic meters per kilogram (m³/kg).

At -17 degrees Celsius, the specific volume is influenced by the properties of the refrigerant being considered, such as R-404A or R-134a. Each refrigerant has its own specific thermodynamic properties which can be found in refrigerant property tables or charts.

The value of 0.0237 m³/kg indicates that for every kilogram of the refrigerant, it occupies a volume of 0.0237 cubic meters at the specified temperature. This measurement is critical for various calculations in refrigeration systems, such as determining the refrigerant's density, pressure enthalpy relationships, and overall system efficiency.

The other values—0.0236, 0.0238, and 0.0239 m³/kg—could represent other specific volumes at slightly different conditions or different refrigerants but are not the correct value for the specified temperature of -17 degrees Celsius in this instance. Thus, the choice of
