What is the temperature at which the pressure reads 18.2 inches of mercury?

• A. 63 degrees Fahrenheit
• B. 59 degrees Fahrenheit
• C. 61 degrees Fahrenheit
• D. 56 degrees Fahrenheit

Answer: (B)

To determine the temperature at which the pressure reads 18.2 inches of mercury, it's essential to understand the relationship between temperature and pressure in refrigeration systems, particularly when using psychrometric charts or tables that relate these two measurements. In many cases, pressure readings in inches of mercury can be correlated directly to temperature values. Typically, this correlation is established by using various empirical data, such as the properties of refrigerants or the specific gas laws that apply to the refrigerants being used in industrial refrigeration systems. In this case, 18.2 inches of mercury corresponds to a specific temperature, and through proper reference to tables or charts that list the properties of the relevant refrigerant, 59 degrees Fahrenheit has been identified as the temperature associated with this particular pressure. This means that at 59 degrees Fahrenheit, the pressure of the refrigerant would be expected to be 18.2 inches of mercury, reflecting the behavior of gases under varying thermal conditions. Understanding these relationships is crucial for operators, as knowing the correct temperature at given pressures aids in effective system monitoring and operational adjustments, ensuring that the industrial refrigeration system functions efficiently.
