You're tracking parcels. So, 42 parcels are tracked each holding 0.1146/42 kg/s.  Each parcel trajectory is calculated based on the diameter & material property you set in the injection. Read up on Parcel Theory for a more complete explanation. 

In Fluent the reports/settings for particle should have been labelled as parcel in most instances. As the terms were muddled up in about v3 there's not much chance of them being corrected.Â
