✦ Synopsis

The Laplace transforms of the output signals from a three-sectional system (i.e., fore-section, investigated vessel and after-section), in which the sections have different diameters, are described for s-function, rectangular and arbitrary input signals by using the axially-dispersed plug flow model. Equations for the mean residence time and the variance of the response of the system are reported. The results could be used to evaluate the axial dispersion coefficient in flow analysis or process systems, for system modelling and optimization.
