Gurley porosity vs sheffield porosity

WebPorosity Porosity is measured (in the U.S.) using a Gurley porosity meter. A test specimen is placed in the Gurley porosity meter that measures the time (in seconds) required for 100 mL of air to pass through one square inch under the applied pressure of 1.22 kPa (approximately 0.177 psi). WebPorosity measurement Gurley consists of a leak proof air reservoir of known volume. A piece of Porosity is measured by using a piece of equipment called a Gurley. The the test sample is clamped with an air tight seal against the mouth of the reservoir. The air in the reservoir is then forced through the test sample at a constant pressure.
