Fixture units and vent sizing

[macheske]

Does anyone have the table for fixture units and the allowed # of fixture units per size of vent? I need to vent the following; 2 toilets, 2 tubs, 3 sinks. I have a 1 1/2" vent and thinking I need to run another 2" vent. I would break it up as: vent #1 (1 1/2) 1 toilet, 1 tub, 1 sink, vent #2 (2") 1 toilet, 1 tub, 2 sinks. vents below the sinks would be wet from sinks.
Thanks,
Rick

rephrase that last comment regarding the sinks...don't quite understand.

if planning to split up the venting as you've mentioned, both lines would have to be a min. 2" (toilets require a 2" vent.) do you have sketch or something showing the layout(s)?
