Which consequence results when exceeding design Reynold’s number within aircraft fuel lines?

A)Increased laminar boundary layer thickness
B)Premature pump cavitation erosion
C)Decreased frictional head losses
D)Enhanced heat transfer efficiency

💡 Explanation

Exceeding the Reynold’s number signifies a transition from laminar to turbulent flow, therefore increased flow disruptions initiate unstable pressure zones leading to the mechanism of cavitation. This creates destructive vapor bubbles that collapse near pump surfaces, rather than a stable flow/optimal cooling.
