Taking into account of entropy generation during evolution of a viscousfluid, we have estimated inverse Knudsen number, ideal hydrodynamic limit forelliptic flow and QGP viscosity to entropy ratio in $\sqrt{s}$=62 and 200 GeVCu+Cu/Au+Au collisions. Viscosity to entropy ratio is estimated as$\eta/s=0.17\pm 0.10\pm 0.20$, the first error is statistical, the second oneis systematic. In a central Au+Au collision, inverse Knudsen number is $\approx2.80\pm 1.63$, which presumably small for complete equilibration. In peripheralcollisions it is even less. Ideal hydrodynamic limit for elliptic flow is$\sim$40% more than the experimental flow in a central collision.
