← ScienceWhich consequence results when the heat load exceeds a cryogenic pump's capacity?
A)Vapor-lock induced capacity reduction✓
B)Increased fluid lubricity and efficiency
C)Reduced thermal counter-conductivity occurs
D)Reverse Brayton cycle re-liquefaction occurs
💡 Explanation
Excessive heat causes boiling within the pump, therefore vapor-lock reduces its capacity to move liquid because the phase transition to gas occupies more volume locally, rather than maintaining liquid volume flow.
