(1)	$\begin{array}{l}\displaystyle j_m(t,l) = j_m = \rm const\end{array}$

where

$\begin{array}{l}j_m\end{array}$

mass flux along the pipe

In case of a Pipe Flow with constant cross-section area $\begin{array}{l}A(l) = A = \rm const\end{array}$ it simplifies to:

(2)	$\begin{array}{l}\displaystyle \dot m(t,l) = \dot m = j_m \cdot A = \rm const\end{array}$

where

$\begin{array}{l}\dot m\end{array}$

mass flowrate along the pipe
