Figure 9 demonstrates the centrality dependence of $E_{T}/N_{ch}$ for Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV. We calculate $E_{T}/N_{ch}$ vs $N_{part}$ using the same value of T and $\mu_{B}$ as used in fitting the hadron ratios with respect to $N_{part}$ at this energy. We compare EV-SHGM predictions with the experimental data [@Adam:2016thv] and find that it could not explain the data over all the number of participants. These findings suggest that
