A hydrodynamical approach has been applied to estimate the expected elliptic flow measured by the azimuthal asymmetry parameter $v_2$, in pp collisions at $\\surd$s = 14 TeV. $v_2$ of $\\pi^-$ is found to be strongly dependent on the parton density profile inside a proton [e.g., surface diffuseness parameter ($\\xi$)]. For $\\xi$ = 0.105, $v_2$ is found to be positive while at $\\xi$ = 0.25, $v_2$ is close to zero and approaches negative values at large $p_t$.
