The result in the video is incorrect. The radius (0.39m) needs to be squared before multiplying by 3.14. Answer is 0.478m squared

Why different colours

I have folowed this step by step and the final .39 squared is .1521m2 times that by 3.14 = .4778m2 not .60m2 Am i missing someting ? did it 10 times same results

Is this the method for measuring DOC concentration by high temperature combustion?

Hello can someone please answer this question for me I'm just learning how to water chemistry for my swimming pool and these vids on UA-cam some of these people are not explaining correctly so I use a photometer pool lab1.0 with a tablet so I'm accurate dpd1 I get my Free chlorine # then I add dpd3 to the tester and I get my Total chlorine # and for the most time my Free chlorine # is always greater than the Total chlorine # so doesn't this mean that I do not have any COMBINED CHLORINE/ CHLORAMINES to Shock from the pool please help with an answer thanks Chris
