Also, I did my calculations based on pie r squared x velocity x 60sec = cubic ft/min

4/12 or 5/12 or 6/12 (dependent on the size of the drop)

(( x /12) / 2 ) squared) x pie x 60 sec x measured velocity in ft/s

For example for a 5” drop I got 100 ft/s

((5/12) / 2) squared ) x pie x 60 sec x 100 ft/s = ~1000 cubic ft/min

And the meter I used was purchased off amazon for $20 so while it may be inaccurate, it swings both ways so it may have overstated or understated the velocity.
