Estimate laminar and turbulent flat-plate boundary-layer thickness and skin-friction coefficients.
Turbulent thickness
0.02 m
24.3 mm at x = 1.50 m
Local Reynolds number
6,162,660.70
based on freestream and plate station
Average Cf comparison
0.00053 / 0.00325
laminar / turbulent flat-plate estimate
Laminar and turbulent correlations give different boundary-layer thickness and skin-friction limits.
Re_x = 6,162,661
Turbulent thickness
24.3 mm
8.1 x laminar estimate
Laminar thickness
3.0 mm
Blasius smooth-plate estimate
Skin-friction ratio
6.1 x
turbulent average Cf versus laminar
