Estimating Service Lives of Organic Vapor Cartridges II: A Single Vapor at all Humidities
Gerry O. Wood
9. Which of the following input parameters is NOT needed for organic
vapor cartridge service life estimation using the new Wood model:
a. Micropore volume of the carbon
b. Liquid density of the chemical
c. Diffusion coefficient of the vapor
d. Carbon bed geometry and weight
10. The effects of relative humidity and adsorbed water on organic
vapor cartridge service life are summarized in the Wood model
by the value of the:
a. Micropore volume of the carbon
b. Water vapor affinity coefficient
c. Organic vapor affinity coefficient
d. Amount of preadsorbed water
The Long-Term Performance of Electrically Charged Filters in a Ventilation System
Peter C. Raynor and Soo Jae Chae
11. For particles 1.03 μm in diameter, the fiberglass filters had an
efficiency of about 95% that changed little with time. A curve fit to
the data for 1.03 μm particles collected by filters made from the
polyolefin fibers shows a minimum efficiency over time of about:
a. 95 %
b. 85 %
c. 70 %
d. 5 %
12. Filters made from charged polyolefin fibers experienced a larger
increase in pressure drop throughout the test than filters made from
glass fibers. True or False?
True
False
Development of Evaluation Procedures for Local Exhaust Ventilation for United States Postal Service Mail-Processing Equipment
Bryan R. Beamer, Jennifer L. Topmiller and Keith G. Crouch
13. Using a particulate counter like the Met One Hand Held Particle
Counter in conjunction with aerosols generated at points of
potential contaminant release is a good method to test capture
efficiency of local exhaust ventilation at mail processing facilities.
True or False?
True
False
14. The methods ultimately used by the authors to evaluate capture
efficiency for local exhaust ventilation include:
a. air velocity measurements
b. smoke release observations
c. high efficiency particulate air (HEPA) filter testing
d. tracer gas experimentation
e. All of the above
f. a, b and d only
