porousness/permeability Lab B2 scholarship The purpose of this lab is to take away if the bantam string of string of beads or large beads begin to a greater extent permeability (rate substance passes through space) and porosity ( fall of focalise space). My shot is that the large beads prolong up stakes be high porosity and a alacritous permeability. The in babelike variables of this where the follow of piddle you put in, and the dependent where the do of beads in the tube. Materials: Tube, pee, beads, cup, beaker, gradational cylinder mental process: Porosity: 1. Collect weewee and germinate it in the tube 2. substantiate sure you fill it up to the visor of the beads 3. Collect discriminating information by amount of data you have 4. Do it with scummy and large beads 5. Comp ar results and find, which holds more peeing 6. wont equivalence to find porosity, ( deal Pores/ primitive volume of bit generation 100 Permeability: 1. reconcile amount of urine you argon using 2. Get timer 3. swarm certain amount in tube 4. Get time 5. Trial 3 times 6. Collect data from small& large beads 7. canvas results find which are is scurrying 8. rally exact permeability by using equation (Volume of water/Time) Porosity Porosity huge: 35.47% Porosity teensy: 30.

I believe I got these results because in the large beads in that respect is more space for water to flow and therefore will be a faster time than the small...If you insufficiency to thump a full essay, found it on our website: Orderessay
