Big Karlo spout flow diagram
Below 1 GPM the flow out of the spout is fairly thin and tends to deteriorate into a rain-like ribbons. The spout can be used this way, but the flows look weak in comparison to the mass of the spout.
Between 1-5 GPM the stream is fairly laminar and flat-ish. It holds together well the majority of the measured fall until it degenerates into a water chain type of flow.
The spout can handle a considerable volume of water beyond 5GPM
Spout was plumbed with 1¼ in. pipe for all tests. The measured flows aren’t as succeptible to changes in pipe size as is the case for some of the smaller spouts.
