The empirical correlation for local mass transfer coefficient for turbulent boundary layer flow past a flat plate is given by

Sh X = 0.332 (Re) 0.5 (Sc) 0.33

Sh X = 0.332 (Re) 0.6 (Sc) 0.33

Sh X = 0.0298 (Re) 0.7 (Sc) 0.33

Sh X = 0.0298 (Re) 0.8 (Sc) 0.33

Sh X = 0.332 (Re) 0.5 (Sc) 0.43

Sh X = 0.332 (Re) 0.5 (Sc) 0.23

Sh X = 0.332 (Re) 0.5 (Sc) 0.33

Sh X = 0.332 (Re) 0.5 (Sc) 0.43

Sh X = 0.332 (Re) 0.5 (Sc) 0.53
