Which outcome occurs when high Reynolds number flow initiates within cryogenic pumps used for liquid hydrogen transfer?

💡 Explanation

Increased Reynolds number means higher fluid velocity, therefore 'cavitation' occurs as reduced pressure causes vapor bubbles that collapse violently. This 'cavitation' erosion is the answer option,  rather than viscosity, turbulence, or the benefits of vortex dynamics, because cryogenic systems are especially prone.
