You can sit down and do the flow calc's of the volume of water the can pass through a 1.25" per hour assuming atmospheric pressure on the water (no head pressure) and assuming no future fiction loss of elbows and pipe past the hole.

Formula is velocity X Area = Flow Rate

115866 ft/hr (gravity) X 0.008522 ft2 (hole dia.) = 987.423 ft3/hr =

7386.4 US gal/hr will drain through a hole 1.25" in diameter. Thats a lot of water.
