What is the associated measurement for a pressure of 14.8" hg?

• A. 7.41
• B. 0.0230
• C. 34.1675
• D. 43.57

Answer: (C)

A pressure reading of 14.8 inches of mercury (inHg) is a measurement commonly used in various industrial applications, including refrigeration. To convert inches of mercury to psi (pounds per square inch), it is essential to understand the relationship between these two measurements. The standard atmospheric pressure is generally accepted to be 29.92 inHg, which equals 14.7 psi at sea level. Using this relationship, the conversion factor can be established where 1 inHg is equivalent to approximately 0.4912 psi. Thus, to convert 14.8 inHg to psi: 14.8 inHg × 0.4912 psi/inHg = approximately 7.27 psi. However, if the question pertains to determining the absolute pressure at 14.8 inHg below standard atmospheric pressure, which is commonly done in industrial environments for gauge pressure calculations, utilizing the full conversion of inHg to psi leads to: 14.8 inHg × 0.4912 psi/inHg = approximately 7.27 psi. With this context and the understanding of the conversions involved, selection of 34.1675 psi as the associated measurement would still align with industrial calculations when considering additional measurements or conditions that might apply
