Abstract: We highlight some connections between the final state hadronic observables and the initial conditions using a recently found new exact family of solutions of relativistic hydrodynamics. These relations provide explicit examples of the scaling behaviour in relativistic hydrodynamics and provide an advanced estimate of the lifetime and the initial energy density in √sNN = 62.4, 130, and 200 GeV Au + Au collisions at RHIC and √sNN = 5.0 TeV Pb + Pb and 5.44 TeV Xe + Xe as well as √s = 7, 8 and 13 TeV p + p collisions at LHC energies. A surprising result is that these advanced estimates yield a non-monotonic increase of the initial energy density with increasing collision energy at the RHIC energy range.
