← TechnologyInside a hydraulic actuator driving a metal stamping press, which risk increases when fluid velocity intensifies?
A)Increased erosive cavitation damage✓
B)Greater thermal expansion rate
C)Reduced actuator response time
D)Elevated fluid bulk modulus
💡 Explanation
Erosive cavitation damage increases because rapidly increasing fluid velocity results in localized pressure drops causing vapor bubble formation and subsequent collapse following Bernoulli's principle. Therefore, material erodes,rather than thermal effects or slow response times impacting performance.
