Suppose you have gotten a new job where you have to design balls that fly through the air with as little resistance as possible. You know that in front of the ball there is laminar flow, so in back of the ball there should be
A) Turbulent flow, because there will be lower density.
B) Turbulent flow, because there will be less drag.
C) Laminar flow, so the leading and trailing pressure environments are similar.
D) No air flow at all.

Laminar flow is a type of fluid flow in which the fluid flows in parallel layers, with no disruption between the layers. In the case of a ball flying through the air, laminar flow is desired in front of the ball because it creates less drag. In back of the ball, laminar flow is also desired because it helps to create a vacuum that pulls the ball forward.
