← ScienceWhich outcome occurs when rapid pressure changes induce cavitation?
A)Increased wear on impeller surfaces✓
B)Improved fluid density measurements
C)Decreased thermal transfer efficiency
D)Enhanced chemical reaction kinetics
💡 Explanation
The decrease in pressures generate vapor bubbles. Violent implosion of nitrogen through the mechanism of cavitation erodes metals, pitting rather than improving surface properties, because bubble collapse creates highly localized shock waves; therefore increased wear results.
