The thickness up to which the velocity approaches 99% of the free stream velocity. The distance measured perpendicular to the boundary by which the free stream is displaced on account of the formation of the boundary layer.
<h3>What is displacement thickness in boundary layer theory?</h3>
The displacement thickness for the boundary layer is defined as the distance the surface would have to move in the y-direction to reduce the flow passing by a volume equivalent to the real effect of the boundary layer.
The thickness of the boundary layer represented by δ is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the mainstream.

Explanation:
As per the question, the given description imply that the chef is making '<u>stencil</u>' cookies as the sheets are assembled together in order to be cut in the desired shape(using stencil comprising of silicon mat and knife) and to be topped by the favorite ingredients. The assembled sheet pan along with a silicon mat would be cut in different shapes to get the desired cookie shape through the use of the offset palette knife, razor blade, and sheet of thin cardboard from the cake box. Therefore, this descriptions justify the deduction that the chef is making <u>'stencil'</u> cookies.
