Viscosity of mixed cyclone gas, mi μLFE = Viscosity of gas laminar flow elements, micropoise. Viscosity of standard air, 180.1 mi Hold = cropoise. 6.2 PM10 Particulate Weight. Determine the weight of PM10 by summing the weights obtained from Container Numbers 1 and 3, less the acetone blank. 6.3 Total Particulate Weight. Determine the particulate catch for PM greater than PM10 from the weight obtained from Container Number 2 less the acetone blank, and add it to the PM10 particulate weight. 6.4 PM10 Fraction. Determine the PM10 fraction of the total particulate weight by dividing the PM10 particulate weight by the total particulate weight. 6.5 Total Cyclone Flow Rate. The average flow rate at standard conditions is determined from the average pressure drop across the total LFE and is calculated as follows: 2. McCain, J.D., J.W. Ragland, and A.D. Williamson.
