What is the pressure reading associated with the second temperature of 36.87?

To determine the correct pressure reading associated with the temperature of 36.87 degrees, one must rely on the relationship between temperature and pressure specific to refrigerants, following principles from the refrigerant's pressure-temperature chart.

For many refrigerants, each temperature corresponds to a specific saturation pressure. In this case, the pressure at 36.87 degrees needs to be directly referenced to standard saturation conditions of the refrigerant in question. If choice A, 1.6122, is determined to correspond with the saturation pressure at that temperature as per the refrigerant’s characteristics, then it stands as the valid answer.

Using the pressure-temperature relationship, it’s essential to consult the right thermodynamic tables or refrigerant saturation charts that provide these precise readings. If 1.6122 is the pressure listed for 36.87 degrees, it accurately reflects the physics of the refrigerant's behavior under those specific conditions, confirming A as the correct answer. Recognizing this foundational interplay between temperature and pressure is crucial for an effective understanding of industrial refrigeration systems.
