I've been doing some testing, messing with a boiler on my test world and I found out that, at least on 1.5.2, tesseracts have an input limit of 100mB/t per side. Meaning that a liquid tesseract has a limit of 600mB/t total for input, they still have no apparent limit for output.
To max out a a HP36 steam boiler using tesseracts, it takes 2 tesseracts taking the steam input with 9 liquiducts attached to the boiler with 480 mB from the second tesseract to spare. If you have 2 boilers it takes 3...
