← ScienceWhich risk increases when a Venturi meter experiences very high fluid velocity?
A)Increased cavitation near throat region✓
B)Reduced frictional head losses
C)Improved pressure recovery downstream
D)Minimized measurement errors overall
💡 Explanation
High velocity causes a large pressure drop per Bernoulli's equation; the mechanism of cavitation occurs because the liquid pressure approaches the vapor pressure, therefore, resulting in vapor bubble formation rather than maintaining liquid continuity at the throat.
