Original Paper


The formation of a laminar boundary layer over a water surface has been experimentally studied for the case of a low wind speed of 3.77 m/s without pressure gradient. Velocity profiles were measured using a small total head tube with an external diameter D=0.7 mm in order to detect the velocity as close to the air/water interface as possible. Precision data were obtained by close attention being paid to near boundary correction procedures arising from the effects of viscous, velocity gradient and wall proximity on the pressure tube. Measurements for the first time support Lock's theory.
