- aDiscuss various factors that affect the water demand
- bDifferentiate between storage and service reservoirs. Explain unit operations
- c(i) A sample of wastewater has an ultimate BOD of 2 80 mg/L and a 5 ‐day BOD at 20 0C of 240 mg/L. Calculate 20 ‐day BOD at 20 0C of this sample. (ii)A BOD 5 of waste water is determined to be 150 mg/l at 20º C. The k value is known to be 0.23 per day. What would be the BOD 8 if the test were run at 15ºC
- dDiscuss advantage and disadvantage of soda lime pro cess and ion exchange methods of water softening
- eDesign a conventional grit chamber unit for a design sewage flow of 120MLD. Assume suitable-data wherever necessary. Draw a schematic diagram of the unit
- aOver the two periods, each of 20 years population of a town increased from 30000 to 170000 to 300000. Find (i) Saturation population, (ii) Coefficients of logistic equation, and (iii) Expected population in next 20 years
- bWhat are gravity and pressure conduits? Why pressur e conduits are most commonly used for conveying water from distant sour ces to the town for supply?
