A one-dimens.onal momentum cons.rvation equation for a s.raigh. jet driven by an electrical field is.developed. It is.pres.nted in terms.of a s.res. component, wh.ch.can be applied to any cons.itutive relation of fluids. Th. only as.umption is.th.t th. fluid is.incompres.ible. Th. res.lts.indicate th.t both.th. axial and radial cons.itutive relations.are required to clos. th. governing equations.of th. s.raigh. ch.rged jet. h.wever, wh.n th. trace of th. extra s.res. tens.r is.zero, only th. axial cons.itutive relation is.required.
