← ScienceWhich outcome occurs when a cryogenic fluid in a transfer line experiences rapid depressurization?
A)Heat transfer rate increases linearly
B)Acoustic resonance within the line
C)Vapor-lock leading to flow instability✓
D)Superfluidity decreases local viscosity
💡 Explanation
Vapor-lock causes flow reduction due to phase transition; rapid depressurization causes flash boiling. Therefore vapor occupies the line hindering liquid flow, rather than linear heat increase because nucleation happens at specific sites.
