City Q has an average water consumption of 22000 m3 / day. Jar tests have indicated that 33 mg / L of hydrated aluminum sulphate "alum" [Al2 (SO4) 3.14H2O] is the optimum dosage required to treat the water supply to this town. The additional alkalinity used is HCO3-. The natural alkalinity in the untreated water source is 57 mg / L as CaCO3. Use the coagulation reaction to:
a. Determine the amount of coagulant used per day (in kg / day)
b. Determine the amount of precipitant generated per day (in kg / day).
c. How much alkalinity is being consumed during the coagulation / flocculation process (in mg / L CaCO3)? Is the natural alkalinity level adequate?

A city planner wants to estimate the average monthly residential water usage in the city. He selected a random sample of 40 households from the city, which gave the mean water usage to be 3411.10 gallons over a one-month period. Based on earlier data, the population standard deviation of the monthly residential water usage in this city is 387.70 gallons. Make a 95% confidence interval for the average monthly residential water usage for all households in this city. Round your...

The mean consumption of water per household in a city was 1212 cubic feet per month. Due to a water shortage because of a drought, the city council campaigned for water use conservation by households. A few months after the campaign was started, the mean consumption of water for a sample of 92 households was found to be 1167 cubic feet per month. The population standard deviation is given to be 220 cubic feet. a. Find the p-value for the...

13. A barge floating in fresh water (Q= 1000 kg/m3) is shaped like a hollow rectangular prism with base area A=550 m2and height H= 2.0 m. When empty the bottom of the barge is located H0= 0.45 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H1= 8 m below the surface. Select the correct free-body diagram for the barge when it is empty. Write an equation for the buoyant...

Life insurance experts have been claiming that the average worker in the city of Cincinnati has no more than $25,000 of personal life insurance. An insurance researcher believes that this is not true and sets out to prove that the average worker in Cincinnati has more than $25,000 of personal life insurance. To test this claim, she randomly samples 100 workers in Cincinnati and interviews them about their personal life insurance coverage. She discovers that the average amount of personal...
