The theory presented in Part I is applied to data for shrinkage of silica gels undergoing syneresis. The dependence of shrinkage rate on sample size, and the shape of the contraction curve, are predicted to depend on the permeability and the viscoelastic properties of the gel network. Measured shrinkage curves are in reasonable agreement with curves calculated from the theory using independently measured values for the permeability, modulus, and viscosity of the gel.
