Which of the following is a reversible pulmonary condition caused by some type of irritant (e.g. dust, pollen) and characterized by bronchial airway narrowing, dyspnea, coughing, and, possibly, hypoxia and hypercapnia?

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 1st beaker is (mg/g):

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 = 1.1 mg/L TCE concentration in the effluent = 50 µg/L The plant operator wants to operate at QA/QW = 2, this operating condition:
