On basis of the film model of crystal growth the relation L = L0 (1 + az) has been derived which describes the dependence of the linear growth rate on crystal size as a function of the dimensionless residence time of crystals z. For the perfectly stirred (MSMPR) crystallizer were then derived relations for the reduced population density of crystals nucleation rate, mean crystal size and distribution of crystal sizes. For very small values of the parameter a all derived relations give numerical values close to those satisfying the McCabe ΔL-law.
