We've encountered that problem numerous times. 

Unscrew the yoke/head assembly from the bowl and reconnect it to the 
bowl with a  2-3 foot length of hose and the appropriate fittings.  Hold 
yoke/head assembly over a 5 gal bucket that has been marked off in  
gallon increments. (We use a janitor's style drum  marked off in 5 
gallon increments for showers).  Activate the eyewash and record time it 
takes to fill the bucket 1 gal and then do the math.  You can also check 
the dispersion at this time with a Haws or Guardian Plexiglas 
gauge...just make sure you hold the yoke/head assembly level to the 
plane of the floor.
