Description This paper presents an experimental procedure and results of velocity measurement in the slip flow regime. The measurements are for nitrogen gas flowing at low pressure (flow Reynolds number: 4-198, Mach number: 0.05-0.12) in a conventional tube of 16 mm internal diameter. The static pressure is measured at the wall of the tube and the stagnation pressure is measured through a Pitot tube, for different mass flow rates. The velocity is estimated by applying stagnation pressure correction proposed by earlier researchers, as the Bernoulli equation cannot be applied in gas flow for Re-P
