← ScienceWhich consequence occurs when exceeding design velocities in a Venturi meter?
A)Inaccurate flow rate measurements occur✓
B)Fluid viscosity will surprisingly decrease
C)Overall pressure recovery is maximized
D)The meter’s differential pressure disappears
💡 Explanation
Turbulence causes lower pressure readings than predicted by Bernoulli's equation because energy dissipates as heat rather than converting fully to velocity. Therefore the flow displayed becomes inaccurate, rather than alternative outcomes that are due to measurement error under ideal conditions.
