Tee-end feeds are recommended every 1,000 ft. (300 m). One reference electrode is recommended for every 50 feet (15 m) of tank diameter. 2. Pt and MMO perform the same in this application. Choice is based on personal preference. 3. Estimates based on 1/3 man-hr. per anode. Experienced crews should take less time. 4.These calculations are based on protecting only one surface. If two surfaces are being protected, double the desired current density. Estimator Created by All calculations are based on this schematic.
