9.48 There are a number of techniques to help people stop smoking, but their cost and effectiveness vary widely. One accepted measure of effectiveness of a program is "percentage of enrollees quitting." The table in this problem shows several techniques touted as effective stop-smoking methods, some historical data on the approximate cost of each program per person, and the percentage of people smoke-free 3 months after the program ended. The Cancer Society provides annual cost-offset funding to cancer patients so more people can afford these programs. A large clinic in St. Louis has the capacity to treat each year the number of people shown. If the clinic plans to submit a proposal to the Cancer Society to treat a specified number of people annually, estimate the amount of money the clinic should ask for in its proposal to do the following: (a) Conduct programs at the capacity level for the technique with the lowest cost-effectiveness ratio. (b) Offer programs using as many techniques…
A tank is fitted with 10 pipes, some of them for filling and some for emptying. Each of the pipes that fill the tank can fill it in 8 hours, while each of those pipes that empty a full tank in 6 hours. If all the pipes are kept open when the tank is full, it will take exactly 2 hours to empty the tank. How many of these pipes are fill pipes?
2. Imagine you are working for the city authority as an environmental engineer. Your treated gray wastewater is released to the nearby river. Community people are receiving their drinking water from the central city pipeline. City authorities are distributing drinking water to your home by treating the river water where you released the treated gray wastewater. As environmental engineering, develop a flow diagram for treating gray wastewater to river water and finally to the drinking water by following the above narrative. 3. Determine the diameter of a single-stage plastic media filter to reduce an applied BOD, from 150 mg/L to 50 mg/L. Use a flow rate of 0.20 m/s and a recirculation ratio of 10.0 along with a filter depth of 1.70 m. The water temperature is 20 °C
