Project Description:
Mathematical modeling can often include the process of writing a di erential equation to describe a physical situation. Almost all of the di erential equations that you will use in your future job are there because at some time someone modeled a situation to come up with the di erential equation that you are using. So far, you have studied the graphs for di erential equations graphically and learned some analytically techniques for solving certain types of di erential equations: separable and linear rst order. This project is designed for you to utilize these skills by focusing on the questions below. You will turn in, on BlackBoard, solutions to these problems that include explanations where applicable.
Many important problems in biology and engineering can be put into the following framework: A solution containing a xed concentration of substance x ows into a tank, or compartment, containing the substance x and perhaps some other substances, at a speci c rate. The mixture is stirred together very rapidly, and then leaves the tank, again at a speci c rate. Find the concentration of substance x in the tank at any time t. Problems of this type fall under the general heading of \mixing problems" or compartment analysis. This project explores this application.
Independent Tanks
1. Create models for the following scenarios:
(a) A very large tank initially contains 15 gallons of saltwater containing 6 pounds of salt. Saltwater containing 1 pound of salt per gallon is pumped into the top of the tank at a rate of 2 gallons per minute, while a wellmixed solution leaves the bottom of the tank at a rate of 1 gallon per minute. Call this tank \Tank A".
(b) Tank B is the same basic scenario as Tank A, but pure water is being pumped into Tank B instead of saltwater.
(c) Tank C is the same basic scenario as Tank A, but the rates are switched: saltwater enters Tank C at a rate of 1 gallon per minute, and leaves at a rate of 2 gallons per minute.
(d) Tank D is the same basic scenario as Tank A, but Tank D initially contains 6 gallons of pure water.
2. Graph the slope elds for each of the di erential equations described in part (1). What do you predict is the long term behavior of the amount of salt in each tank for di erent initial conditions?
3. Solve initial value problems that correspond to individual Tanks A, B, C, and D. Use a plot to compare four solution curves and discuss how these curves predict/represent outcomes you predicted from the description of each scenario and the graphs in part (2).
Dependent Tanks
You have been given a pair of large tanks with saline solution. Tank E began with 3 pounds of salt in 14 gallons of water. A saline mixture containing 4 pounds of salt per gallon ows into tank E at a rate of 2

gallons per minute. The tank is kept well mixed, and ows out of tank E into tank F at a rate of 2 gallons per minute. Tank F initially contained 31 gallons of fresh water, and the tank is kept well mixed, and that mixture if pumped out at a rate of 2 gallons per minute.
1. Using the above description, write down a di erential equation, with an initial condition, for the amount of salt in tank E. Use s_{E} to represent the salt in tank E.
2. Write down a di erential equation, with an initial condition, that gives the amount of salt in tank F. Use s_{F} to represent the salt in tank F .
3. After the tanks have been mixing for one hour, a leak is sprung in tank F, so that an additional 1
gal/minute is owing out of the tank. Call the time that the leak sprang time t = 0. For the sake of this problem, we will relabel this leaky tank as tank G. Let s_{G} be the salt in tank G. Write a di erential
equation, that describes the amount of salt in tank G. What is the appropriate initial condition for tank s_{G}? Explain your answer.
Real World Application
Many real world problems can be thought of as a \mixing problem", i.e. the analysis of a single \compartment" into which some substance is owing at a certain rate and out of which the same substance is owing at some, probably di erent, rate. Examples of such situations include: chemical mixtures, pollution, gaseous mixtures and even some organ functions. Research and discuss, in a few paragraphs, a \real life" scenario that can be modeled as a mixing problem.

10. Gamma Corporation is considering the installation of governors on cars driven by its sales staff. These devices would limit the car speeds to a preset level, which is expected to improve fuel economy. The company is planning to test several cars for fuel consumption without governors for 1 week. Then governors would be installed in the same cars, and fuel consumption will be monitored for another week. Gamma Corporation wants to estimate the mean difference in fuel consumption with a margin of error of estimate of 2 mpg with a 90% confidence level. Assume that the differences in fuel consumption are normally distributed and that previous studies suggest that an estimate of sd=3sd=3 mpg is reasonable. How many cars should be tested? (Note that the critical value of tt will depend on nn, so it will be necessary to use trial and error.)
