Capillary flow data for a polypropylene melt exhibiting a positive exit pressure are analyzed using the normal Bagley correction procedure. The results obtained by this method are shown to be the same as those derived by the Hagenbach‐Couette procedure. The agreement is exact because the Bagley procedure implicitly involves a linear extrapolation to zero exit pressure. Thus it is not necessary to subtract the exit pressure from total pressure drop as suggested by other workers. The Bagley procedure correctly adjusts data obtained for polymer melts in capillary flow experiments even if a positive exit pressure exists.
