Air stripping process is used as a pump and treat method for removing a trichloroethylene (TCE) from groundwater.  The following conditions apply: Influent flow rate = 40 m3/sec QA/QW = 20 Dimensionless Henry’s constant = 0.2 TCE concentration in the influent = 2.1 mg/L TCE concentration in the effluent = 50 µg/L Amount of pollutant (TCE) in the influent entering the air stripping tower is (Kg/sec):

100 mL of a solution with a TOC (total organic carbon) concentration of 0.5% is placed in each of the five containers with activated carbon and shaken for 48 hours. The samples are filtered and the concentration of TOC measured, yielding the following analyses: Test beaker no.:          1          2          3          4          5 Carbon (grams):          10        8          6          4          2 TOC (mg/L):               42        53        85        129      267   The Freundlich isotherm is to be used:  X/M = k Cf 1/n The value of X/M in the 5th beaker is (mg/g):

PART TWO – Descriptive Essay: Choose ONE topic from the following options and write an essay of approximately 300-500 words (slightly more is ok). Use specific details and examples in your answer. (30 points) Describe the development of the Cold War from the 1940s to the 1990s. Describe the development of the Civil Rights Movement from the 1920s to the 1970s.

A series LC circuit contains a 100-mH inductor, a 36.0-mF capacitor and a 12-V battery. What is the frequency of the electromagnetic oscillations in the circuit? Give your answer in Hz(Hint: Recall the difference between frequency and angular frequency)

A high-voltage powerline operates at 500 000-V rms and carries an rms current of 500 A. If the resistance of the cable is 0.050 Ω/km, what is the resistive power loss in 200 km of the powerline? Report your answer in MW (mega watts).

A long solenoid (radius = 3.0 cm, 2 500 turns per meter) carries a current given by I = 0.30 sin(200πt) A, where t is measured in s. When t = 5.0 ms, what is the magnitude of the induced electric field at a point which is 2.0 cm from the axis of the solenoid?  Express your answer in mV/m (millivolt per meter)(Hint: be careful which radius you use to calculate the time derivative of the magnetic flux)

Which of the four cases are best explained by state-centered factors? Why?
