  1. Find a resonance frequency (minimal break off distance), then vary the sheath pressure to optimize the jet using this calculator.
  2. The current jet velocity v is distance / time where distance is the span from the bottom of the last attached drop (breakoff) to the same point on a drop n drops below, and time is the number of drops in the span x the drop period (1/ddf). The optimal frequency fopt is calculated:

           fopt = v / 4.5dj

       where the estimated contracted jet diameter dj is 0.975 x the nozzle diameter dd. See reference for more.
