RESUMO

We consider m finite pipes with constant transversal section and é dependent diameter. This pipes will be filled with incompressible fluid in stationary regime. ln the exterior extremes of each pipe, boundary pressure values are given. Beside the proof of existence and unicity of solution, we exibit an aproximated solution. This aproximated solution behavior like a Poiseuille flow on the extremes of the pipes and an solution of a linear Leray problem elsewhere. Finally, we present the rate of convergence with é tending to zero
