Summary The effect of length on the average heat transfer from a tube to a fluid in turbulent flow inside it is studied for that condition where turbulence at the entrance to the heat transfer tube is fully developed. The analysis of the experimental data available shows that the factor S in the equation h av =h(1+SD/L) is not constant but varies with both L/D and Re. The theoretical S varies also with L/D and Re. Deissler's values vary in the same way as the experimental ones but Latzko's values vary in the opposite direction. The experimental S for air and water could be represented by the equation $$\frac{S}{{(L/D)^{0.3} }} = \frac{{6000}}{{Re}} + 0.55.$$
