Final answer:
Laminar flow is the type of quick and silent airflow that occurs in streamline, characterized by smooth, parallel streamlines and minimal resistance.
Step-by-step explanation:
The type of air flow that occurs in streamline and is quick and silent is called laminar flow. Laminar flow is characterized by smooth, parallel streamlines where the air moves in orderly layers with minimal mixing and resistance.
This contrasts with turbulent flow which includes swirls and eddies that imply more resistance to flow. Ceiling fans with smooth blades would generate less noise and be more efficient compared to those with decorative features that interrupt the smooth flow of air.
