← ScienceWhich effect limits peak flow rate through small injectors at high frequency?
A)Increased viscous pressure drop✓
B)Kinetic energy dissipation
C)Reynolds number elevation
D)Wall contact electrification
💡 Explanation
Increased viscous pressure drop occurs because momentum transfer increases near the walls. This increased momentum transfer restricts maximal flow rate through small spaces; therefore, the flow is viscosity-limited rather than inlet pressure limited.
