Which wb's cooling charactaristics have you found to be describable by Sieder- Tate?
I have yet to employ Sieder-Tate successfully for any wb.
E.G.

Used Billa's data* and obtained Convection Coeff using my own Waterloo and Kryotherm Excel plots.
Dunno but possibly seeing a corruption of the Womac** correlation
