Effective porosity ratio concerns porosity at the wheel surface. Effective porosity is defined as the effective pore volume of the pores to the volume of the wheel on the wheel surface as shown in Fig. 10.11.The effective porosity is different from the overall porosity within the wheel structure defined by Eq. (10.1).

Get Price### Analysis of Green Roof Growing Media Porosity

Porosity is defined as the ratio of void volume to the total solid volume of a material. Plant roots must access both air and water to survive. As with natural soil, ideally, 50 percent of the growing media should consist of mineral and organic content. The remaining 50 percent should be pore space. In this ideal situation, the pore space present in a growing media would be divided evenly ...

Get Price### Porosity - Wikipedia

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and . Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).

Once a void marker peak is injected, you can use the following formula to determine column void volume: Retention time of void peak (V o) * Flow Rate. Example: If an acetone peak retains at 2.32 min, and the flow rate is 0.85 mL/min, then: V o = 2.32 min * 0.85 mL/min. V o = 1.972 mL.
