the mass of 2 GeV and repulsive interactions by assigning the geometrical hard-core size to each baryon. Mesons are treated as pointlike particles in our model. We also incorporate the collective flow in our model to explain the experimental data at various energies particularly at LHC energies. In ref. [@Prorok:2004af], the statistical model is also used to study the transverse energy per charged particle at midrapidity with longitudinal and transverse flows for the wide range of energies from AGS to RHIC. In our case, we do not take volume as a free parameter and extend our analysis upto LHC energies, where the role of collective flow is more pronounced than at lower energies. In addition, we study the centrality dependence of $E_{T}/N_{ch}$ at top RHIC and LHC energies, which is related to the chemical freeze-out of the system. We study the energy dependence of the associated observables like the participant pair normalized-$\frac{dE_T}{dy(\eta)}$, the Bjorken energy density ($\epsilon_{Bj}$) in order to study the created system at different energies and the possible different behaviour at LHC energies, which could serve the purpose of ruling out and/or establishing different production mechanisms. In our model calculation, we assume that the chemical and thermal freeze-outs
