Question:

A pulse of concentrated NaCl solution is introduced as tracer into the fluid entering a vessel (V = 1 m³, v = 1 m³/min) and the concentration of tracer is measured in the fluid leaving the vessel. Develop a flow model to represent the vessel from the tracer output data sketched in Figs. P12.1 to P12.6
