The laminar boundary layer equation describes the behavior of a laminar boundary layer, which forms when a fluid flows over a solid surface. In this region, the fluid moves smoothly in parallel layers, with minimal mixing between adjacent layers. The Blasius solution provides an expression for the boundary layer thickness ($\delta$) as a function of distance from the leading edge of the plate ($x$),

Where:

• $\delta (x)$ is the boundary layer thickness at a distance $x$ from the leading edge of the plate (m),
• $\nu (x)$ is the kinematic viscosity of the fluid (m²/s),
• $U$ is the free-stream velocity of the fluid (m/s).
