← ScienceWhich outcome reduces accuracy reading flowmeters approaching laminar-turbulent transition?
A)Decreased thermal boundary layer thickness
B)Increased velocity profile asymmetry✓
C)Elevated fluid kinematic viscosity values
D)Lowered critical surface tension coefficients
💡 Explanation
Increased velocity profile asymmetry occurs because, at the relatively near critical Reynolds number range, viscous damping diminishes therefore transitional boundary layer vortices distort readings, rather than producing a predictable average flow as in fully turbulent flows.
