\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
the L\&L's ``weak momentum injection''
assumption \citet[][page 88]{1959flme.book.....L}.) assumption.) Yes it is 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 Where does the {\it nonequilibrium} stuff happen? There is no mention of linear response or anything like that.
\end{enumerate}
