Which effect limits peak flow rate through small injectors at high frequency?

💡 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.
