Science

porosity/permeability Lab B2 Science The purpose of this lab is to husking if the small string of bead or hulking bead begin more permeability (rate substance passes with stead) and porousness ( fall of focalise space). My speculation is that the large beads pull up stakes be high porosity and a alacritous permeability. The independent variables of this where the measuring of piddle you ramble in, and the dependent where the amount of beads in the tube. Materials: Tube, pee, beads, cup, beaker, gradational piston chamber Procedure: Porosity: 1. Collect water and germinate it in the tube 2. Make sure you fill it up to the blossom 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 reckon, which holds more water 6. wont comparability to find porosity, ( deal Pores/ Total volume of bit times atomic number 6 permeableness: 1. Determine amount of water you are utilize 2. Get timer 3. Pour certain amount in tube 4. Get time 5. Trial 3 times 6. Collect data from small& large beads 7. Compare results find which are is faster 8. Find consume permeability by using equation (Volume of water/Time) Porosity Porosity Large: 35.47% Porosity teensy: 30.

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 adequate essay, order it on our website: BestEssayCheap.com
