A rarefied gas flow trough a long circular tube due to pressure is studied on the basis of the Holway linear ellipsoidal model kinetic equation. The diffuse reflection model is used as the boundary condition on the channel walls. The mass flow rate is calculated as a function of the small pressure gradient. Similar results presented in the literature are compared.
