Abstract
Exact expressions are presented for the corrective terms for a one-dimensio nal fin temperature and heat lost when the insulated tip assumption is used for the case where the tip is maintained at a constant temperature. Both s traight rectangular and an uniformly thick annular fin geometries are discu ssed. Numerical examples are shown to highlight the considerable error in a ssuming an insulated tip condition.
