The use of pressure drop measurements for estimating ventilation and paper porosity/Verwendung von Zugwiderstandsmesswerten zur Abschätzung von Ventilation und Papierporosität

In our recent article on the above-mentioned topic, the derivation of the pressure drop equations was based on the first approximation that diluting air flow is constant over the length of a filter or tobacco column. While this is a reasonable approximation for filters and tobacco columns with low l...
