According to the data given in the illustration, which of the following would be the physical state of the fluid at a gage vacuum of 25.03 inches Hg, and 126.08 degrees Fahrenheit? Illustration SG-0026

Correct Answer: Option B — Sub cooled liquid.

Comparing the measured vacuum and temperature against saturated steam tables indicates that the actual fluid temperature is below the saturation temperature corresponding to that pressure, classifying the fluid as a subcooled (compressed) liquid.
