← ScienceWhich risk increases excessively when airflow through a Venturi meter exceeds equation accuracy?
A)Erroneous differential pressure measurement✓
B)Increased laminar flow instability
C)Boundary layer detaches gradually
D)Systematic kinetic energy reduction
💡 Explanation
When airflow exceeds limits within a Venturi meter, increased turbulence causes deviations from ideal fluid behavior. This violates the assumptions necessary for Bernoulli's equation. Therefore, differential pressure deviates from expected values, rather than inducing kinetic energy loss, because viscous effects are now relevant.
