1. Exhaust gas from a particular automobile contains 1.25% by volume of carbon monoxide. Express this concentration in mg/m 3 at 1 atm pressure and 25°C temperature. 2. Five million gallons per day (MGD) of wastewater, with a concentration of 10.0 mg/L of a conservative pollutant, is released into a stream having an upstream flow of 10 MGD and pollutant concentration of 3.0 mg/L. [This problem shows the typical U.S. practice of using non-metric units for most everything except small concentration values and standards.] a. What is the concentration in ppmm just downstream? b. How many pounds of substance per day pass a given spot downstream? 3. A lake with constant volume 10 × 10 6 m 3 is fed by a pollution-free stream with flow rate 40 m 3 /s. A factory dumps 5 m 3 /s of a nonconservative waste with concentration 150 mg/L into the lake. The pollutant has a decay rate coefficient K of 0.25/day. Assuming the pollutant is well-mixed in the lake, find the steady-state concentration of pollutant in the lake.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
