← ScienceWhich error overwhelms pitot tube velocity calculations when increased?
A)Non-constant fluid density develops
B)Viscous stress becomes relevant✓
C)Compressibility effects reduce
D)Thermal expansion becomes excessive
💡 Explanation
Increased fluid velocity causes turbulence; therefore viscous forces dominate, invalidating the Bernoulli equation's ideal fluid assumptions, because the inviscid approximations no longer hold. This answer is correct; a turbulent regime must incorporate Reynolds stress rather than negligibly-small estimations.
