A correction factor for the theoretical fin efficiency of serrated fins, reported in the 1st and the 2nd report, was derived for inline arrangement experimentally. The experiment was performed using an open-type wind tunnel with six kinds of test finned-tubes made of copper, carbon steel and stainless steel, which were arranged in one to five rows. Heat transfer measurement was done by the local thermal simulation method. The derived correction factor for the 1st row was the same as for staggered arangement reported in the 3rd report, for the deeper rows, however, a further correction was needed to add, which may be caused by the difference in the non-uniformity in heat transfer coefficient over the fin surface.
