\item Payam has (equation 12) $v_{\rm DNA}=F_{\rm ext} \ln(\ell/d)/\eta\ell - \lambda E\ln(1+r_{\rm D}/d)/\eta$, which we use to calculate $t_{\rm D}$. He finds $t_{\rm D}\sim \ell\eta/E\lambda$ -- whence this simplification?  \end{enumerate}  \item {\it Is the elongated jet derivation valid?} (Since integration along length of the DNA may break L\&L's ``weak momentum injection'' assumption.) assumption.)\\  Yes it {\bf  is valid }valid  -- this is explicitly addressed on pp. 2-3: the criterion for the submerged jet formulae to be valid is the same as the criterion for linear fluid velocity dependence. \item Is there anything to learn from the inevitable energy dissipation -- from the electric field to the viscous fluid. How much work is done?
