Reactor Design 373

Table 7.5 gives the calculation procedure. Any reaction kinetics, indicated by
Equation 7.4.4, can be used in the procedure. For each reactor in the series, we
assume

1. perfect mixing
2. constant volume
3. constant temperature
4. constant density
5. constant heat capacities
6. equal mixer power for each reactor
