I read that it would take 80,000 square inches of red copper oxide, to create enough voltage to be useful. How many pounds of red copper oxide would that amount to? Please show me the math so I can learn from this, thanks.
1 square meter is equal to how many pound
It depends on the thickness of your sheet. I will use the thickness of a copper atom as an example: it is about 2.3 x 10*-10 m in diameter First, lets convert over to SI. 1 sq meter 39.37 in/m x 39.37 in/m 1550 sq in/sq m 80,000/1550 51.61 sq m of copper oxide Second, the volume length x width x height 51.61 is length x width 2.3 x 10*-10 m is height You multiply them and find you have 1.19 x 10*-8 cubic meters of copper. The density of copper oxide(Cu2O) is 6.0 g/cc change this to kg/cc 6 g/cc x 1 kg/1000 g x 10*6 cc/m*3 The density is 6000 kg/m*3 Third, calculate the mass using density and volume. M DV 6000(1.19 x 10*-8) 7.12 x 10*-5 kg To convert kg to lbs, multiply by 2.2 lbs/kg 0.000157 lbs (if the oxide is the thickness of an atom) You can sub in the thickness you actually need where I used the thickness of an atom.that's only the minimum amount of material you would need.hope that helps. Edit: not hard to fix. The area is 80000 m*2 x 2.3 x 10*-8 m 0.00184 m*3 mass density x volume 6000 x 0.00184 11.04 kg 11.04 kg x 2.2 lbs/kg 24.3 lbs Hope you get this before you repost.
