Question

I have read that non-laminar flow reduces drag on blunt bodies.

Given that, why is pitting not used on motor vehicles?
Options:
A) Pitting increases drag on vehicles, counteracting the benefits of non-laminar flow.
B) Pitting disrupts the airflow, causing turbulence that significantly increases drag.
C) Pitting on motor vehicles adversely affects stability and handling.
D) Pitting creates surface irregularities leading to increased air resistance and reduced efficiency in non-laminar flow.

Answer 1

Pitting is not used on motor vehicles because it disrupts the airflow and causes turbulence, significantly increasing drag on the vehicle.

Step-by-step explanation:

Non-laminar flow refers to turbulent flow, which occurs when the layers of fluid mix and there are significant velocities in directions other than the overall direction of flow.

This disruption in the flow causes turbulence and significantly increases drag on a body. That is why pitting is not used on motor vehicles, as it would create surface irregularities and disrupt the airflow, leading to increased drag and reduced efficiency in non-laminar flow.
