- A wastewater treatment plant receives 250 mg/L BOD, 45 mg/L NO3-N, and 0.08% TSS. What is the loading of each component (lb/d) if the plant flow is 730,000 gpd?Evapotranspiration in an 8 ha farm is 7 mm/day and percolation losses is 2 mm/day. What is the design discharge of a canal to be able to deliver a 5-day requirement of the farm in 24 hours if irrigation efficiency is 75%? Select one: a. 200 m3/hr b. 175 m3/hr c. 150 m3/hr d. 140 m3/hrDrinking water from a dam which undergoes conventional treatment has a computed chlorine demand (due to silt, corrosion and bacteria) amounting to 3.5 ppm. Per PNSDW, such drinking water must have a mandatory chlorine residual of 1.0 ppm at source. If production flow is at 500 cu.m./day, calculate the chlorine dosage needed in pounds per day (PPD).
- The storage tank of your plant has a 1.20 million gallon capacity and the demand is 0.40 million gallons per day (MGD). If the pump was broken, how many more days could your plant supply the water?A small community had a population of 65000 and 85000 in the census year of 1991 and 2001 respectively. Assuming a geometric growth rate and an average water consumption of 300lpcd, Calculate the design flow for the treatment plant and the transmission mains. Select an appropriate value of design period. I will report and downvote wrong answersAn 800-square-kilometer basin recorded 50 cm of rainfall in a year. During that year, ET was 5 meters, and recharge by ponds to the groundwater was 2.5e^7 cubic meters. Domestic pumping was 35 cubic meters/day and underflow from the basin was a loss of 25 cm. What is the total change in storage in this basin (give the answer in cubic meters per year)?

- Problem 1A 300-house residential development is proposed. Assume that each person uses 500 liters on average eachday. Suppose that four people live in each house. Calculate how many more liters of water per day onaverage that will need to be supplied.A Semi-solid waste storage has a volume of 1145 m3. The basin is initially 71% empty. The semi-solid density is 1521 kg/m3 is taken away from the storage tank at a rate of 5211.81 kg/day. How long will the basin take to be 91% emptied? Assume the storage is now initially full 23% and re-estimate the time to empty itl. The diversion requirement of a 5-ha farm was estimated to be 10mm/day during peak periods. If the pumping plant has a 60% efficiency, how many kilowatt-hour energy is required to lift water 5 meters?
