Which flow change follows if fuel injection Reynolds number increases?

A)Laminar becomes turbulent fluid flow
B)Wall surface tension reduces
C)Fuel viscosity drastically decreases
D)Pressure drop along fuel rail stabilizes

💡 Explanation

Increased Reynolds number indicates inertial forces dominate viscous forces; therefore, transition to turbulence occurs, because increased kinetic energy disrupts laminar flow, rather than the other options describing unrelated fluid characteristics.
