Abstract
The influence of Sb on the fouling factor was
considerable only for the tUbes with the highest
fin-height (1. 5 mrn) •
At both clean and fouled conditions, the highest
enhancement ratios were corresponding to 1.0 mm Ih
comparing to 0.5 and 1.5 mID Ih •
The maximum enhancement ratio, (Ufo /U) was 1.45 for I.n p
the clean condition while it was 1.36 for the fouled.

factor, Rf at the0.140 m2K/kW and
0.125 m2K/kW at fluid velocity of 0.34 m/s and 1.0 m/s respectively. Also, the later value of Rf can be taken for the finned surface, when a suitable inter-fin.
