渗透率是具有膨胀孔隙相的材料的宏观性质，例如许多岩石和过滤器。我们描述了一个简单的实验，使用低成本的方法类似于达西所使用的渗透率的经验测定。我们主张使用可控的圆柱形烧结过滤器，其中有作为孔隙度的函数的渗透率的理论约束，对经验结果可以进行比较。这里介绍的方法提供了一个逐步的实验室实验和数值技术的方法，用于拟合线性方程的数据，是适合本科物理，地球科学或工程courses.Permeability是一个宏观性质的材料与膨胀孔隙相，如许多岩石和过滤器。我们描述了一个简单的实验，使用低成本的方法类似于达西所使用的渗透率的经验测定。我们主张使用可控的圆柱形烧结过滤器，其中有作为孔隙度的函数的渗透率的理论约束，对经验结果可以进行比较。这里介绍的方法提供了一个逐步的方法，以实验室实验和数值技术拟合线性方程的数据，是适合本科物理，地球科学或工程课程。
Permeability is a macroscopic property of materials with a percolating pore phase, such as many rocks and filters. We describe a simple experiment for the empirical determination of permeability using a low-cost method similar to that used by Darcy. We advocate the use of controlled cylindrical sintered filters, for which there is theoretical constraint of the permeability as a function of porosity, against which empirical results can be compared. The methodology presented here provides a step-by-step approach to laboratory experiments and numerical techniques for fitting a linear equation to data and is appropriate for undergraduate Physics, Earth Science, or Engineering courses.Permeability is a macroscopic property of materials with a percolating pore phase, such as many rocks and filters.
