Summary

A variational principle for lower bounds on the time-averaged mass flux in an incompressible channel flow with uniform wall injection and suction is derived from the incompressible Navier-Stokes equations. With appropriate test background flow fields, the explicit estimates for the friction coefficient are produced and discussed.
