At 62 degrees Fahrenheit, what is the pressure reading?

To determine the pressure reading at 62 degrees Fahrenheit, it’s essential to refer to the appropriate pressure-temperature relationship for refrigerants. The values provided represent readings in inches of mercury (in. Hg), which is a common unit of pressure measurement.

At 62 degrees Fahrenheit, the correct pressure reading that corresponds to the saturated condition of a specific refrigerant (usually a common refrigerant like R-134a) can closely match the answer choice of 19.4 inches of mercury. This value indicates that at this temperature, the refrigerant is in a state where its vapor pressure is equal to this specific measurement, reflecting a balance between the liquid and vapor phases.

This pressure is particularly important in the context of industrial refrigeration systems, where maintaining the correct pressure is crucial for efficient operation and system integrity. Understanding these values enables refrigeration operators to make informed decisions about the operation and performance of refrigeration systems, ensuring they can maintain optimal conditions and troubleshoot effectively if pressures vary.

The other pressure readings provided in the choices do not correspond to the expected saturation pressure at 62 degrees Fahrenheit and thus would not be used in typical operational scenarios for that temperature in relation to standard refrigerants.
