I don't know where OP got $2 per 1000 liters (maybe locally sourced product) but if you can import them in bulk you could potentially get it down to $0.50 per 1000 liters.
As for double dosing ClO2 what I would do is use an effective dose that's on the lower end like 0.25-0.30mg per liter and...
Thanks for the confirmation, I'm just replying to say that 100mg was indeed the correct answer.
If you don't mind me asking, how did the wording confuse you?
Homework Statement
A is a stable powder
B is water
C is the product of the powder being in contact with water.
A is soluble in substance B and for every gram of A 10% is C.
For a concentration of 0.5ppm of C in twenty liters of water how many grams of A do you need?

You don't need to show the working out, our teacher likes to give his students a problem to solve where the answer isn't so obvious from a google search.
For getting the right answer you get first pick of seats for the new year and our names get put into a raffle to win one of those space...
I wrote exactly what was in the question, and it's not possible to go check this as the academic year is over and school is closed.
So the threshold ionization energy of hydrogen is 13.598ev right?
One thing that I didn't write was that the answer should be in V/m.
So I think that the...
Homework Statement
Calculate the threshold ionization intensity for hydrogen gas.
The attempt at a solution
The way I tried to work it out was to use the field intensity of air which breaks down at, 3x10^6V/m. The ionization potential of oxygen is 13.618ev, 14.534ev for nitrogen and 13.598ev...
As someone asked in one of the previous posts, this thread is regarding a subcritical reactor using an added source of neutrons. I'm just doing research for an upcoming 4000 word essay that I will have to write about power.
In one part of the essay you're meant to come up with a plan to do...
Yes I only would like to know about neutron production methods that is not fission based, as in a fission reactor a lot of the neutrons are consumed in the reactor itself.
What about D-D fusion to make the neutrons, it's more difficult to do but you don't have to have an extra layer for...
I think I need to be more specific, and I'll split it into 2 parts.
What is the best/easily achievable way of producing 1x10^18n/s (fast)?
For the above 'best way' how much power would you need?
What I would like to know is how much power do you need to produce 1x10^18n/s if you were fusing deuterium and tritium and it doesn't have to break even or be even close to breaking even, I just want to know how much power it would take to produce that many neutrons per second and because D-T...
Basically as the title says, what type of fusion would give the highest number of neutrons for a given amount of power.
Also am I correct in assuming that most fusion methods will always produce more neutrons than other neutron sources such as americium-beryllium?
(There are probably some...
Actually I did talk to both my school library and my local library before I posted this and they both said that they couldn't help.
The school basically said that because it is my own research I would have to pay for any research material.
The paper is from 2002 and the only other place that...
Hi,
I'm writing an assignment for school and there is a paper on springerlink which looks like it could be of help to me, the site wants me to pay $45 for the single article but I think that for subscribers it is free.
So I was wondering if anyone who is already a subscriber is willing to...
Hi everyone
I’m doing an engineering course at school and we need to write a 2000 word essay on why engineers have failed society (you can choose to agree or disagree)
The description for the essay is:
Engineers have failed society by designing products that have high energy consumption and...
