Genuine science: the continuity relation, dynamic pressure, and Reynolds number are standard textbook fluid-mechanics expressions.
Engineering-inspired reconstruction: duct segments, honeycomb, static-pressure ports, wing balance, and downstream axial fan show real installation concepts, without claiming to copy a particular facility.
Simplified educational model: constant-density flow, fixed rectangular test area (2.75 × 2.35 scaled metres), and textbook dynamic viscosity μ = 1.81 × 10⁻⁵ Pa·s. No wall losses, boundary-layer corrections, or empirical fan efficiency are calculated.
Illustrative animation: moving streamlines, rotor spin, wing incidence and flow-speed visuals are not validated CFD, wind-tunnel calibration, aerodynamic forces, or safety guidance. A pressure identity provides an independent arithmetic check, not an experimental verification.
