← ScienceWhich erroneous result arises using Bernoulli's equation with a non-Newtonian fluid?
A)Kinetic energy predicts pressure accurately.
B)Velocity profiles estimate cross-sectional variance.
C)Calculated pressure drops exceeds actual.✓
D)Flow rates reflect laminar boundary layer.
💡 Explanation
Increased viscosity in non-Newtonian fluids causes greater energy dissipation via viscous friction, therefore the calculated pressure drop is erroneously lower, because Bernoulli's equation neglects shear thinning behaviour, therefore underestimates actual drop, rather than assuming kinetic energy accurately predicts it.
