Which outcome occurs when the static pressure reaches vapor pressure?

A)Cavitation erodes pump impeller material
B)Reynolds number remains substantially constant
C)Laminar flow becomes more dominant
D)Bernoulli’s equation always remains valid

💡 Explanation

Cavitation occurs as the local low pressure induces rapid boiling. The mechanism is vapor bubble formation and collapse, which release energy because mechanical shock erodes the surfaces; therefore, causing damage rather than maintaining constants or flow regime.
