I have a doubt.. here in 2nd question, they have asked for BOD of the sample after 5 days right ? So we should find remaining BOD only right.. instead of finding BOD5 ?

Concentration of organic matter in a sealed water sample after remaining in dark for 4 and 8 days at 20 °C is calculated to be 160mg/L and 60mg/L respectively. ? (CLO-1,PLO-1,C1) (15 marks) a) Calculate value of k at 20 °C and at 25 °C.

Sir, is there any calculation of DO when I use dilution water for titration with winkler method?

Why is B - B' taken as the BOD_5 for the wastewater? Shouldn't it be multiplied by the dilution factor?

@physicslover-nitwarangal4821 4 жыл бұрын

in the last question you calculated BOD5 of sample as 38 and BOD5 of mix is 48 this means BOD5 of water should be 10.but in question it is given that drop in dissolved oxygen is 2.so how it is possible. please explain me i am very confused

@abisheksaju5585 4 жыл бұрын

in the last question what is wrong if we just subtract the 'bod of dilution water (2) 'from the 'bod of diluted sample (48) ' taking dilution factor for dilution water as 1 because dilution water is not mixed with anything else right....??

Sir I have a doubt In the previous video for finding average BOD you didn't considered 0 in the calculation reasoning as we are not sure whether it happened on day 5 or any other day so neglecting the data. but in the first problem of this video you included 0 in the calculation for initial DO of mix.

@dcrust3231 5 жыл бұрын

see carefully,,0 is not involve

@civilenggmcq7926 7 жыл бұрын

i am not getting the difference between (initial D.O. of mix-final D.O. of mix) at 03:34 and drop in D.O.of bottle mix at 16:06 as both the containing waste water and dilution water initially and finally. and thank u for such videos

@APSEDUVERSE 7 жыл бұрын

I did not understand your doubt clearly but let me try to explain. The final BOD value of waste cannot be computed by experiment if it is not mixed with dilution water because the waste water alone does not have sufficient oxygen so that we can find out the oxygen consumed in 5 days and that is why for the final value you will always be given the BOD of mix and if the dilution water also has some BOD value then that also will be given separately.

@Himanshunov 6 жыл бұрын

First of all thank you sir, I have one confusion here, since 'diluted sample' mean 'mixture of waste water sample and aerated water' And 'diluted water mean diluted sample' then how the term 'mix' is different from 'dilution water'.

@saihemanthpetluri331 6 жыл бұрын

'dilution water'. water which is used for the dilution of the sample. 'mix' solution formed after mixing the dilution water with the sample.

If initial DO of waste is 0(negligible) then how to find BOD of waste in the last question?

Yes..I had some urgent work that's why didn't upload any video for last 2-3 days. I will resume in 1-2 days.
