Abstract: Navier-Stokes(NS) equations of viscosity flow were expressed with Lattice-Boltzmann method in low Mach number range and a 7 Bit-FHP model. The population distribution, thefunction of the density distribution of Poiseuille pipeline flow and the simulating solution was presented. the relaxation timeτ
was determined under the small Knudsen number.The solution of the simulation was in agreement with the analytical solution.

Key words: Lattice-Boltzmann Method, Navier-Stokes equations, density distribution, poiseuille flow
