Abstract

In the presence of perfect fluid with bulk viscosity homogeneous isotropic Friedmann Cosmologies are studied in the scale covariant theory of gravitation. Using special law of variation for Hubble’s parameter, a class of solutions is found. The physical properties of the model are also investigated.
