-%SUMMARY hPipe: Pipe with heat transfer and heat storage.
+%SUMMARY hPipe: Pipe for compressible fluid with heat transfer and heat storage.
+
+%DESCRIPTION hPipe represents an ideal (energy conserving) pipe carrying a
+%DESCRIPTION fluid with heat transfer. To ensure energy conservation, power bonds are used and
+%DESCRIPTION connected by (energy conserving) TF components.
+%DESCRIPTION It is assumed that the working fluid is an ideal gas (gas constant r) and that a mass
+%DESCRIPTION m_t is stored within pipe with a volume v_t.
+
 %DESCRIPTION Parameter 1: m_t (mass in pipe)
 %DESCRIPTION Parameter 2: v_t (volume of pipe)
 %DESCRIPTION Parameter 3: r (gas constant)
 %DESCRIPTION Typical lable entry 
 %DESCRIPTION % Component type hPipe
