This element implements the option to use constand, flow rate independet propertes. Both, the pressure loss coefficient and the heat transfer coefficient are set to the constant values: $$\zeta=\zeta_c$$ $$\alpha=\alpha_c$$
Please be aware, that the geometric properties $l$, $V$ and $S$ are used as they are configured, without checking any conflicts. Hence, the parameters could be set s.t $S\neq l\cdot U$ and $V\neq l\cdot A$, where $U$ and $A$ are the circumference and cross sectrion area acording to the configured profile.
