It is shown that (1) quasi-adiabatic conditions can be reached in the column; (2) the bulk-to-tube heat transfer coefficients for each U-tube downward and upward sections may or may not differ significantly, depending on the way uncertainty of the measurements is estimated; (3) using the different measurements and uncertainty estimates for given conditions, a mean heat transfer coefficient over all tubes is estimated within +/- 5%. The consequences for bulk-to-tube heat transfer coefficient prediction in a larger column are discussed. %G English %L hal-01923761 %U https://univ-lyon1.hal.science/hal-01923761 %~ CEA %~ UNIV-SAVOIE %~ UGA %~ CNRS %~ UNIV-LYON1 %~ DRT %~ LITEN %~ LGPC %~ CEA-GRE %~ UDL %~ UNIV-LYON %~ USMB-COMUE %~ INES
