← ScienceWhich inaccuracy occurs when increased viscosity violates Bernoulli's equation?
A)Increased form drag around bluff bodies✓
B)Decreased hydrostatic pressure measurement accuracy
C)Overestimation of turbulent kinetic energy
D)Boundary layer separation point is delayed
💡 Explanation
Increased viscosity means viscous forces cause momentum dissipation, increasing form drag, because the assumption of negligible viscosity underpinning Bernoulli's equation is substantially violated; therefore drag increases, rather than any other flow property being affected under ideal conditions.
