Abstract:
A stainless steel 'T' joint was used to simulate stagnant volume in a pipe-line. Residence time distribution in the lines was measured using a radiotracer (Cr51) which emitted γ radiation. The radiation was measured externally to the pipe line. From the experimental data the dead volume of the system was calculated. The effect of the depth of T and flow velocity on dead volume was evaluated. Labelled bacteria were used in some experiments instead of chromium. No significant difference in behavior between ionic chromium and bacteria labeled with chromium was found. © 1979 Springer-Verlag.
