Question
how many pounds of 65% hth chlorine are required to disinfect a 6 inch water main, 600 feet long with 50 ppm chlorine dosage
If you mean to fill the entire pipe with the chlorine mixture,
I will assume that 6 inches is the diameter. Half of the diameter
is the radius, so the radius is 3 inches and I will assume it's a
round water main.
600 length of pipe feet
0.25 radius feet
3.1416 pi
1728 cb in/cu ft
0.65 density of chlorine in solution given
454 gm/lb
2.54 cm/in
50 parts chorine
1,000,000 total parts
117.8097245 volume ft³
0.00005 chlorine density desired, 50 parts per million
0.005890486 amount of chlorine ft³
10.1787602 amount of chlorine in³
15.65963107 solution needed in³
256.6153766 solution needed cm³
256.6153766 amount of solution * gm
0.565232107 amount of solution lbs
little over 1/2 lb amount of solution
* Assumes 1 cc is one gram;
It is with true water, but I'm not sure here.
I did it in Excel and imported it in.
Note that desnisty was done in metric
due to the conversion on cc to weight.
I noticed that this said it was in trig - is it really?
