System hPipe::Pipe for compressible fluid with heat transfer and heat storage.

hPipe represents an ideal (energy conserving) pipe carrying a fluid with heat transfer. To ensure energy conservation, power bonds are used and connected by (energy conserving) TF components. It is assumed that the working fluid is an ideal gas (gas constant r) and that a mass m_t is stored within pipe with a volume v_t. Parameter 1: m_t (mass in pipe) Parameter 2: v_t (volume of pipe) Parameter 3: r (gas constant) Typical lable entry pipe none m_p;v_p;r
