WebMeasurement of porosity The technology of thin sections or of to-mographic imaging can produce a visualiza-tion of pore space and solid material in a cross-sectional plane, as in Figure 1. The summed area of pore space divided by total area gives the areal porosity over that plane. An analogous procedure can be followed along WebGurley porosity is an expression of air flow rate. Expressed as the time taken for a certain volume of air to pass through a specific filter area under a certain pressure.
WebThe Gurley No. 4250 H-P-S Tester measures a given air flow through the sample for porosity tests and leakage across its surface (s) for smoothness tests. This is accomplished by changing a variety of adapter and clamping plates. This model is identical to the No. 4150 and 4240 for porosity tests and their components.
