Corrosion of electrolytic tough-pitch copper pipe was determined in aerated 2.1N sulfuric acid at 30~ A closed loop circulating system was used, with 1 in., 3/4 in., and 1/2 in. diameter test sections. There was a gradual increase of corrosion rate with increasing Reynolds number in the laminar flow regime, Re ~ 2100; a rapid increase in corrosion rate with increasing Reynolds number in the low turbulent flow regime, Re 2100 to 10'; and a relatively constant corrosion rate due to polarization at Reynolds number ~10'. Reynolds number as a corrosion parameter permitted useful generalizations and comparisons with published heat and mass transfer correlations.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
