How to solve 2nd ques equation in virtual calcy
@sriharishmudholkar2804 2 жыл бұрын
I came across this question, where they are asking to find the distance from the point of discharge, at which the DO would be minimum when waste water is discharged into the river. Given are D.O of waste water, BOD-5 of both waste and river water De - oxygenation constant of both, discharge of both, Which de- oxygenation constant should be considered? velocity of river.

@12.4 (to convert /hour to /day) sir you mention divide by 24.. but we suppose to multiply.. pls correct if I was mistaken..

Bro the way he divided is correct because it will get reciprocaled and get multiplied.

If in the question it is mentioned deoxygenation rate constant how to know if it is base e or base 10?

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.

aditya sir in avg BOD quest ....i have reffered a coaching material and ans they have given is 109.8mg/l. its confusing
@APSEDUVERSE 7 жыл бұрын
Yes! I am aware of that but what I have told is correct. If it says clearly that the BOD becomes zero on the 5th day then you can take it to find out the average but here nothing like that is mentioned so you can do it as I have mentioned. Sorry for the late reply.

Dear sir sample is tested after 5 day we found DO zero ....it may be consumed in 1 or 2 or 3 or 4th day ......so the third result will give misleading result..so we should not use this?

@gauravpandey5297 7 жыл бұрын
Sir in the 2nd question BOD for 5days was given as 180mg/l but you have used the same value of BOD for 2.5days also can we do it like that also? Because i hope BOD will change from 2.5 to 5days
@APSEDUVERSE 7 жыл бұрын
BOD also depends upon the Temperature because the bacterial activities depend on the temperature and as the Temperature increases bacterial activity also increases upto 60 degree Celsius. The BOD value for 5 days is given for a temperature of 20 degree Celsius and if you increase the temperature then same value of BOD can be exerted in lesser time so the question asks the temperature at which the BOD5 = BOD2.5
