← ScienceWhich mechanical failure occurs when hydraulic system flow violates Bernoulli's equation?
A)Pump cavitation and reduced effectiveness✓
B)Increased fluid viscosity and drag
C)Valve lockup due to thermal expansion
D)Seal rupture from friction generated heat
💡 Explanation
Pump cavitation occurs because fluid pressure drops locally according to Bernoulli's equation at constrictions, leading to vapor bubble formation; therefore cavitation damages pump components; rather than viscosity increases or thermal effects which are secondary.
