Calculate the area minus the spraybar and you have it.

Paul, this is from a chart I've used over the years, based on a ST NVA (0.157 dia.)...hope this helps:

Venturi .126 = Restrictor .250
           .148 =               .270
           .159 =               .280
           .170 =               .290
           .181 =               .300
           .192 =               .310
