Lab exp.. Porosity and Permeability..

 Porosity is space between and permeability is rate of flow. Both are like the same because both have to do with the lab or the experiment. we used Porosity and permeability for the lab because we needed to know how faster and slower was the water flowing and the space between the sediment type, obviously the fastes was gravel because when we put the gravel in the tube there were spaces between because there were rocks..
