We provide a minimal strategy for the quantitative analysis of large class non-equilibrium systems in {statistically} steady state using short-time Thermodynamic Uncertainty Relation (TUR). From trajectory data obtained from experiments, we demonstrate how can simultaneously infer quantitatively, both thermodynamic force field acting on system, as well (potentially exact) rate entropy production. benchmark this scheme first an experimental study colloidal particle system where exact analytical results are known, before applying it to case hydrodynamical flow field, neither nor numerical available. In latter case, build effective model based our results. cases, also that match with those another recently introduced [Phys. Rev. X 10, 021009].
