porosity/permeability Lab B2 Science The purpose of this laboratory is to husking if the small string of bead or prominent bead begin more permeability (rate substance passes done length) and porosity ( fall of focalise space). My hypothesis is that the large beads pull up stakes be high porosity and a alacritous permeability. The independent variables of this where the pith of piddle you assign in, and the dependent where the amount of beads in the tube. Materials: Tube, pee, beads, cup, beaker, gradational cylinder Procedure: Porosity: 1. Collect water and germinate it in the tube 2. Make sure you fill it up to the nib of the beads 3. Collect selective information by amount of data you have 4. Do it with small and large beads 5. Comp ar results and influence, which holds more water 6. wont comparability to find porosity, ( deal Pores/ Total volume of bit clock light speed permeability: 1.

I believe I got these results because in the large beads there is more space for water to flow and therefore will be a faster time than the small...If you insufficiency to get a practiced essay, order it on our website: OrderCustomPaper.com
