TEST REPORT FOR HY-C COMPANY, LLC Report No.: 104415176MID-002AR2 Date: 11/09/21
TUNNEL VELOCITY/FLOWMEASUREMENT The tunnel velocity is calculated from a center point Pitot tube signal multiplied by an adjustment factor. This factor is determined by a traverse of the tunnel as prescribed in EPA Method 1. Final tunnel velocities and flow rates are calculated from EPA Method 2, Equation 6.9 and 6.10. (Tunnel cross sectional area is the average from both lines of traverse.)
Pitot tubes are cleaned before each test and leak checks are conducted after each test.
PM SAMPLING PROPORTIONALITY Proportionality was calculated in accordance with ASTM E2515. The data and results are included in Appendix C.
DEVIATIONS FROM STANDARD METHOD: Use of ALT-134 for output rate categories. SECTION 8 TEST CALCULATIONS NOMENCLATURE FOR ASTM E2515: A
= Cross-sectional area of tunnel m2 (ft2).
B ws = Water vapor in the gas stream, proportion by volume (assumed to be 0.02 (2.0 %)). C p = Pitot tube coefficient, dimensionless (assigned a value of 0.99). c r = Concentration of particulate matter room air, dry basis, corrected to standard conditions, g/dscm (gr/ dscf) (mg/dscf). c s = Concentration of particulate matter in tunnel gas, dry basis, corrected to standard conditions, g/dscm (gr/dscf) (mg/dscf). E T = Total particulate emissions, g. F p = Adjustment factor for center of tunnel pitot tube placement. F p = V strav /V scent K P = Pitot Tube Constant, 34.97 s 𝑚𝑚 ec [ � 𝑔𝑔 𝑔𝑔 ∎𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚� ( 𝑚𝑚𝑚𝑚 𝐻𝐻𝐻𝐻 ) ( 𝐾𝐾 )( 𝑚𝑚𝑚𝑚 𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤 ) ] 1 2 or = Pitot Tube Constant, 85.49 s 𝑓𝑓 e 𝑓𝑓 c [ � 𝑙𝑙 𝑙𝑙 𝑙𝑙 𝑙𝑙 −𝑚𝑚𝑚𝑚𝑚𝑚𝑚𝑚� ( 𝑖𝑖𝑖𝑖 𝐻𝐻𝐻𝐻 ) ( 𝑅𝑅 )( 𝑖𝑖𝑖𝑖 𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤 ) ] 1 2 L a = Maximum acceptable leakage rate for either a pretest or post-test leak- check, equal to 0.0003 m3/min (0.010 cfm) or 4 % of the average sampling rate, whichever is less. L p = Leakage rate observed during the post-test leak-check, m3/min (cfm). m p = mass of particulate from probe, mg. m f = mass of particulate from filters, mg. m g = mass of particulate from filter gaskets, mg.
