A 'figure of merit' was defined in order to compare spined pipe performance to other heat transfer surfaces (bare tubes, helically finned tubes, plate finned tubes). Comparisons were performed using three different bases: heat transfer per unit blower energy, heat transfer per unit frontal area, and heat transfer per unit weight. Generally, plate finned tubes performed better than the other surfaces at large spacings, while the spined pipe performed the best at smaller spacings.
