A novel method for quantifying tortuosity by analyzing the pressure distribution of gas within a rotating porous bed is presented. The method utilizes a custom-designed disc-shaped cell packed with activated carbon particles and subjected to a high-speed rotation of 5000 rpm under an equilibrium initial pressure of 5045 mbar CO₂. The theory related to this method is outlined. From the radial pressure distribution, the apparent tortuosity is estimated to be ~2.3. This value is independently validated using an extracted apparent diffusion coefficient of D_app = (9.7 ± 0.3) × 10⁻⁷ m²/s and a corresponding tortuosity of τ_app = 2.2 ± 0.8. The findings establish a new route for probing the interplay between pore geometry, gas transport, and adsorption phenomena under centrifugal forces.
