A water treatment plant effluent is to be disinfected with chlorine from ton cylinders of compressed gas. The plant is 5 million gallons per day. There are a total of 10 useable cylinders in the plant. if the water is chlorinated with a dose of 2 milligrams per liter, how long will the cylinders last until empty? if the gas were to be replaced with liquid sodium hypochlorite (bleach), how many gallons would be required to last the same time as the gas? The sodium hypochlorite solution strength is 15 percent by weight and has the same unit weight as water (specific gravity 1.0). One pound of sodium hypochlorite has the same disinfecting strength as one pound of chlorine gas.
Calculate the pH of a buffer solution prepared by mixing 8.5g KH2PO4 with 43.5g K2HPO4 in 1 liter of water (this is actually the composition of the dilution water used in a BOD test. Follow the same procedures you have been using for previous acid/..
Assume that there were 1,100,000 vehicles making a 28.5-mi round trip per day, the average vehicle emission rate for VOCs is 1.3 g/VM , and the molecular weight of the VOC emissions from the mobile sources can still be represented by that of metha..
A present sum of $50,000 at an interest rate of 12% per year compounded quarterly is equivalant to how much money 8 years ago
Five years ago, GSI, an oil services company headquartered in Texas, issued $10 million worth of 12% 30-year bond with the dividend payable quarterly. The bonds have a call date of this year if GSI decides to take advantage of it.
Estimate the amount of Ca(OH)2(s) leached from concrete during a one-year period by precipitation. Assume that the area receives 40 in/yr of precipitation which is in equilibrium with PCO2= 10^-3.5 atm and [SO42-] = 10^-4 M.
During a 5 hour storm event, the precipitation over a 230-acre area is 1.5niches. There is constant infiltration at a rate of 0.12 inches/hour and the depession storage is 17 acre-ft. Is there any runoff from the area during the storm
Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in a rectangular street repair area of 2000 ft*48ft*6in.
Soil material is being assessed as a possible liner for a sanitary landfill. A soil core was collected and brought to the laboratory. A 10-cm tall section of soil has 2 cm of water continuously ponded on it. The area of the core surface is 78 cm^2..
