The temperature of 20°C is used to take BOD of _________

The temperature of 20°C is used to take BOD of _________ Correct Answer 5- days

The temperature of 20°C is used to take BOD of 5 days because in 5 days the dissolved oxygen present in water is consumed for the decomposition of organic matter. Hence 5 day BOD is used as a standard to represent the amount of oxygen dissolved.

The BOD5 of an effluent from a coke oven plant is 25 mg/L, and the effluent discharge is 4 ML/d. The receiving stream has a BOD5 of 2 mg/L and the stream flow is 40 ML/d. What will be the BOD5 in the stream just below the mixing zone?
An Investigator interviewed 100 students to determine the performance of three drinks milk, coffee and tea. The investigator reported that 10 students take all three drinks, 20 students take milk and coffee, 30 students take coffee and tea; 25 students take milk and tea; 12 students take milk only. 5 students take coffee only and 8 student take tea only. Then the number of students who did not take any of the three drinks is λ. The value of \(\frac{\lambda }{4}\) is equal to

If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that
