This paper gives experimental details of the residence time distribution in cylindrical vessels with length to diameter ratios 1:1, 2:1 and 3:1, length from 0.5 to 4‐ft, and co‐linear axial inlet and outlet nozzles of 1/8 to 1‐in. diameter. The inlet jet was always turbulent with inlet Reynolds numbers in the range 3000 < Re < 10,000. A theoretical model is proposed which predicts the residence time distribution from vessel dimensions and fluid properties only without any empirical correlations. The experimental results show that the larger the scale of the reactor the more valid is the model.
