← ScienceWhich error arises when applying Bernoulli's equation to choked nozzle flow?
A)Density variations become significant✓
B)Viscosity effects overwhelm inertia
C)Surface tension becomes non-negligible
D)Thermal expansion misrepresents dimensions
💡 Explanation
Applying Bernoulli's Equation assumes incompressible flow, it fails when a nozzle chokes because density changes drastically increase passing sonic velocity. Therefore, compressibility errors become substantial, rather than inertial or dimensional properties causing deviations in fluid mechanics predictions.
