Abstract
We compute the longitudinal hydrodynamic flow in ultrarelativistic
heavy ion collisions at 
= 5500 GeV by using boost non-invariant
initial conditions following from perturbative QCD. The transfer of
entropy and energy from the central region to larger rapidities
caused by boost non-invariance is determined and the associated decrease
in the lifetime of the system is estimated.
