Which consequence results when laminar flow assumptions violate Bernoulli's equation?

A)Turbulence and increased viscous drag
B)Decreased flow velocity at constriction
C)Accurate pressure drop predictions obtained
D)Increased flow rate within pipe

💡 Explanation

Violation implies increased Reynolds number. This causes transition to turbulence increasing viscous drag because momentum diffusion becomes dominant; therefore turbulence occurs, rather than maintaining undisturbed parallel fluid layers which leads to an inaccurate result.
