CF 13.25″ to CF 10.0″ reducer

1 × CF 13.25″ (DN250CF), 1 × CF 10.0″ ConFlat flanges, 3,934.1 cm³ of internal volume and 1,214.4 cm² of wetted surface.

Build a system with this part

Its internal volume and surface area feed the pumpdown simulation, and its 3D characterization sets how it affects pumping speed.
