← ScienceWhich outcome occurs when fluid velocity exceeds design limits in a Venturi nozzle used for fuel control?
A)Inaccurate mixture ratio control✓
B)Increased fuel pump efficiency
C)Improved atomization characteristics
D)Reduced risk of vapor lock
💡 Explanation
Inaccurate mixture control occurs because exceeding velocity limits introduces turbulence, violating assumptions in Bernoulli's equation, therefore computed pressure drop will deviate, affecting fuel metering, rather than improved atomization which requires stable flow.
