In this paper we study generalized Chaplygin gas which has viscosity for the case of arbitrary alpha. We obtained modified time-dependent energy density due to bulk viscosity and generalized Chaplygin gas. We have obtained the energy density in terms of alpha, and also we plotted it with respect to time by different alpha.
