Further models of flow-mixing systems

This is recognisable as a series combination of two unequal size CSTRs together with a pure time delay. 

From Example 1, we know the form of tracer response and by plotting this out may estimate that the magnitude of the time delay tj is approximately 1 min. We also know that, for the tracer data, M] = 8.128 min and T2 = 29.008 min (see p. 237). Then 

In Example 4, we calculated the conversion from the RTD directly this was for a first-order reaction with rate coefficient 2.617 x 10 s . Converting this value to min and setting the Laplace variable equal to this value 

This figure corresponds well with the conversion predicted previously on p. 245.
