Dispersion String Test {Ans: The name for one method of visual airflow characterization testing is? A. Constant Flow B. Dispersion String Test C. Turbulent Theory Test D. None of the above}A. True {Ans: An Aerosol Photometer, as per CETA, should have the following parameters: " A calibrated Aerosol Photometer capable of indicting 100% upstream concentration with an aerosol of between 10 and 90 µg/L of polydispersed diotylphthalate (DOP), polyalphaolefin (PAO) or an equivalent fluid. Unit must have a threshold sensitivity of at least 10 µg/L and be capable of measuring concentrations over a range of 10^5 times the threshold sensitivity. The sampling rate shall be 1 CFM (28.3 lpm) (+/-100%) with an inlet probe having sufficient area (1.7 in^2) (11.0cm^2) as to maintain a probe inlet velocity of 90 fpm (0.46 m/s) or slightly higher."
