What is the value of specific volume at a pressure of 18.2 inches of mercury?

To determine the specific volume at a pressure of 18.2 inches of mercury, one must refer to thermodynamic tables or use equations that relate pressure and specific volume for a given substance.

Specific volume is the volume occupied by a unit mass of a substance and it typically varies with pressure and temperature. The value of 0.0228 is representative of specific volume under specific conditions, reflecting what is expected for a typical gas at that pressure. It is common practice to look up or calculate specific volume in order to ensure accurate understanding, especially in industrial refrigeration contexts where precise conditions can affect system performance.

Values for specific volumes are usually given for ideal gases and can be adjusted for real gases under the conditions of interest. Therefore, in this scenario, the value of 0.0228 aligns well with what would be found in established data for common refrigerants or working fluids at this pressure, indicating that it is a reasonable estimate for the specific volume at 18.2 inches of mercury. It's essential to consult the proper resources in an industrial setting to verify these kinds of values when performing calculations or analyzing systems.
