+   The acausal bond graph of system \textbf{Pipe} is
+   displayed in Figure \Ref{Pipe_abg} and its label
+   file is listed in Section \Ref{sec:Pipe_lbl}.
+   The subsystems are listed in Section \Ref{sec:Pipe_sub}.
+
+The \textbf{Pipe} component represents one way flow of incompressible
+fluid though a pipe. Externally, it has true energy bonds: $P$/$\dot V$
+(Pressure/volume-flow) representing hydraulic energy and $T$/$\dot
+S$(Temperature/Entropy-flow) representing convected thermal energy.
+
+Internally, however, the thermal part is represented by a pseudo bond
+graph which computes the flow of internal energy $\dot E$ from the
+upstream temperature $T_1$ and the volumetric flow rate $\dot V$ as:
+\begin{equation}
+  \dot E = \rho c_p T_1 \dot V
+\end{equation}
+The $AF$ component makes the $FMR$ component use $T_1$ rather than
+$T_1-T_2$.
+
+The two \textbf{ES} components provide the conversion from true to
+psuedo thermal bonds and vice versa.
