### Purpose & model
|
||
|
||
Fluid duct with **friction pressure drop** (Darcy/Colebrook-style or equivalent implementation) and near-isenthalpic or adiabatic energy transport:
|
||
|
||
```
|
||
ΔP = f(L, D, ε, Re, ṁ, ρ)
|
||
h_out ≈ h_in (or with small heat loss if modeled)
|
||
```
|
||
|
||
### Residuals & `n_equations()`
|
||
|
||
Pressure-drop residual + energy residual (typically **2** on a series branch).
|
||
|
||
### Ports
|
||
|
||
`inlet` / `outlet`.
|
||
|
||
### Calibration
|
||
|
||
`z_dp` (or equivalent) scales ΔP when exposed via calib — default **1.0**.
