What is the pressure at 58 degrees Fahrenheit?

To determine the pressure at 58 degrees Fahrenheit, it is important to understand the relationship between temperature and pressure in refrigeration systems, particularly when working with refrigerants. In industrial refrigeration, the pressure-temperature relationship is critical, as each refrigerant operates within a specific pressure range at given temperatures.

When looking at typical refrigerant pressure tables, one can find that at 58 degrees Fahrenheit, the corresponding pressure falls around the value of 19.7 inches of mercury (hg). This information is derived from standardized refrigerant pressure charts that outline the saturation pressures of various refrigerants at specific temperatures.

Using these charts is essential for operators to ensure that systems are running efficiently and to diagnose any issues. Hence, the value of 19.7" hg aligns with the expected operating conditions for many common refrigerants at that temperature, making it the accurate choice.

It is important to verify which refrigerant is in use, as the pressure readings will vary by refrigerant type, but in this instance, the answer reflects accepted values within industry norms.
