  In this paper, a spatially homogeneous and anisotropic Bianchi type V model
filled with an imperfect fluid with bulk viscosity and particle creation, is
investigated within the framework of General Relativity. Particle creation and
bulk viscosity have been considered as separate irreversible processes. The
energy- momentum tensor is modified to accommodate the viscous pressure and
creation pressure which is associated with creation of matter out of
gravitational field. Exact solutions of the field equations are obtained by
applying a special law of variation of Hubble parameter. Using this assumption,
we obtain two types of cosmological models. We find a singularity in the first
model whereas second model is non-singular. Further we separately study the
bulk viscosity and particle creation in each model considering four different
cases. The bulk viscosity coefficient $\zeta$ is obtained for Truncated, Full
Causal and Eckart theories in all cases. All physical parameters are calculated
and thoroughly discussed in both models.
