What it calculates
The “Boundary Layer” calculator computes Boundary Layer in mm from 3 parameters: flow velocity (m/s), distance from leading edge (m), kinematic viscosity, ×10⁻⁶ (air 15.1, water 1.0) (m²/s).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Flow velocity = 2 m/s, Distance from leading edge = 1 m, Kinematic viscosity, ×10⁻⁶ (air 15.1, water 1.0) = 15.1 m²/s the result is 13.74 mm.
