than you for your kind answer.
My question is more related to know if theres any rule or formula to estimate a statistically-significant particle-to-parcel ratio?. As you can see, for a fixed dpm mass a decrease of 1order of magnitude in d_p, involves a factor x1000 in the particle-to-parcel ratio. Is there any threshold of this ratio for which the #parcels become unsufficient to accurately represent the physical particles in my system?
