Abstract
In this paper both exponential and power law solutions for the flat Ro bertson-Walker cosmological model have been derived in a generalized B rans-Dicke theory, where the parameter omega is a function of the scal ar field, along with a bulk viscous fluid. The solutions are obtained in Dicke's revised units and these are also given in the original atom ic units via the conformal transformation prescribed by Dicke.
