The DPM concentration is defined as: DPM concentration = (Avg. particle mass in cell * Part resi. Time * Strength of particle) / Cell volume ...1 Strength of particle = number in parcel / dt_flow ...2a = total particle flow rate / mass of single particle in the stream ....2b From equation 1 and equation 2b, DPM conc. = (Avg. particle mass in cell * Part resi. Time * Total particle flow rate) / (mass of single particle in stream * cell volume).....3
