  In this paper we are to study homogeneous and anisotropic Bianchi type-V
universe in presence of bulk viscous fluid source of matter with time function
gravitational constant G and cosmological term lambda. The viscosity
coefficient is regarded as power function of matter density in the first case
whereas in other case it is considered as proportional to the scale of
expansion. Physical realistic solutions of the field equations are obtained by
using a fractional form of Hubble's parameter, which leads an early
deceleration and late time acceleration of the universe. Certain physical and
geometrical behaviors of the model are also studied.
