Laminar entry flow (flow in the inlet length) of a viscous incompressible fluid between two co‐axial cylinders is studied on the basis of linearized Navier‐Stokes equations. It is assumed that the velocity of the fluid is uniform at the entrance cross section. Formulas for the longitudinal components of the velocity and pressure gradient are obtained, and inlet length is calculated.
