Such a setup mimics typical experimental situations in nano/micro-fluidics. During the the translocation process if the monomers in the channel can sufficiently quickly assume steady state motion, we observe the scaling $\\tau\\sim N/F$ of the translocation time $\\tau$ with the driving force $F$ per bead and the number $N$ of monomers per chain.
