1. This question is an application of unsteady state material balances to real life situations. Your special Bull’s coffee mug is filled with twelve ounces of coffee that contains 200 mg of caffeine. Caffeine is eliminated from the body at a rate of dm c,system/dt = -0.116m c, system where m c, system is the mass of caffeine in the body. After you chug down your mug of coffee, how long will it take for the caffeine in your body to drop to 100 mg? You drink one 12-oz mug at 7 AM and another at 3 PM. Plot the caffeine content of your body as a function of time for a 24 hr interval. If you have trouble falling asleep at 12PM, would it help much to cut out the second mug? What are some of the other options you have to deal with sleep deprivation?
