%X We investigate the Bianchi type-V bulk viscous barotropic fluid cosmological model with variable gravitational constant G and the cosmological constant Λ, assuming the condition on metric potential as A'/A=B'/B=C'/C=m/tn, where A, B, and C are functions of time t, while m and n are constants. To obtain the deterministic model, we also assume the relations P = p - 3ηH, p =γρ, η=η0ρs, where p is the isotropic pressure, η the bulk viscosity, 0≤γ≤1, H the Hubble constant, η0 and s are constants. Various physical aspects of the model are discussed. The case of n = 1 is also discussed to compare the results with the actual universe.
