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 29.00 inches Hg, and 85.21 degrees Fahrenheit? Illustration SG-0026
AI Explanation
The correct answer is C) Superheated vapor.
At a gage vacuum of 29.00 inches Hg and a temperature of 85.21 degrees Fahrenheit, the fluid would be in a superheated vapor state. This is because the temperature and pressure conditions are above the saturation point of the fluid, meaning the fluid is in a superheated state and not a saturated liquid or a mixture of liquid and vapor.
The other options are incorrect because a gage vacuum of 29.00 inches Hg would not result in a subcooled liquid (A) or a saturated liquid (B), and the temperature and pressure conditions are not within the two-phase region, ruling out a mixture of saturated liquid and vapor (D).
