From our previously obtained shear viscosity to entropy density ratio (η/s) in the framework of clustering of color sources (Color String Percolation Model: CSPM), we calculate the jet quenching parameterq and trace anomaly ∆ = (ε − 3p)/T 4 as a function of temperature. It is shown that the scaledq/T 3 is in agreement with the recent JET Collaboration estimates. The inverse of η/s is found to represent ∆. The results for ∆ are in excellent agreement with Lattice Quantum Chromo Dynamics (LQCD) simulations. From the trace anomaly and energy density ǫ, the equation of state is obtained as a function of temperature and compared with LQCD simulations. It is possible that there is a direct connection between the η/s and ∆. Thus the estimate of transport coefficient η/s providesq and ∆ as a function of temperature. Both ∆ and η/s describe the transition from a strongly coupled QGP to a weakly coupled QGP.
