I’ll walk through it again, as you are probably right, and I can find the mistake.
1800g is the estimate weight of 450gml silver powder.
The total weight is 1464g.
There is 250ml (g) of water at the top of the container, which we subtract from the total weight, leaving 1214g of a silver/water slurry.
1800g should be the weight
1214g is the weight.
(Here is the mistake) The weight difference is 516g, which is the weight of the missing silver in the slurry, not the weight of the water in the slurry.
So, I would need to convert 516g to an approximate volume of silver powder. Since we have volume, we can now compute the weight of the water in the slurry.
Literally, yes. They are engines that search data. You could index the web on them if you really wanted.
As to how they are used, correctly or not, I consider them closer to databases than “search engines” in the context of this post.
Seeing ES or OS in the same category as Gigasearch needed some distinction though.
