Question 228Steam Plants - 1st Asst/Chief

The correct answer is B) Sub cooled liquid. At a gage vacuum of 25.03 inches Hg and a temperature of 126.08 degrees Fahrenheit, the fluid would be in a sub cooled liquid state. This is because the given conditions place the fluid below the saturation curve on the pressure-temperature diagram, meaning the fluid is in a liquid state at a temperature lower than the saturation temperature for that pressure. The other answer choices are incorrect because: A) Superheated vapor requires the fluid to be above the saturation curve, C) Mixture of saturated liquid and vapor occurs at the saturation curve, and D) Saturated liquid occurs precisely at the saturation curve, not below it.
