The Sherwood number correlation for laminar flow over a flat plate is ShL=0.664ReL^0.5 Sc^(1/3). Expressed as the Chilton-Colburn jD factor, this is
- AjD=0.664
- jD=0.664ReL^(−0.5)
- CjD=0.664ReL
- DjD=0.664ReL^0.5 Sc^(2/3)
Explanation
jD=Sh/(ReSc^(1/3))=0.664ReL^0.5Sc^(1/3)/(ReL·Sc^(1/3))=0.664ReL^(−0.5).
