← ScienceWhich outcome occurs when a throttling valve experiences rapid, uncontrolled pressure decrease in wet steam?
A)Steam superheat increases significantly
B)Steam temperature remains relatively constant
C)Steam dryness fraction rapidly decreases✓
D)Liquid mass fraction temporarily decreases
💡 Explanation
Steam quality degrades because the Joule-Thomson effect induces condensation; decreasing the dryness fraction. Steam expands, therefore reduced pressure allows lower temperature two-phase existence, rather than superheating, without significant effect to liquid mass.
