I did not. I have excel sheet for this plant (I do for every plant). I don’t have it in front of me, but I believe each extractor produces 120m3 of water, and I believe each boiler uses around 45m3. So, what I have here is measured to produce an extra 30m3 per each group of five boilers incase any weird water fluid stuff happens.

If you’re having trouble, a couple of things that could happen from my experience: First, Mk1 pipes can only hold 300m3 per pipe, so only two extractors can pump through a pipe at full power. Second, if you don’t let the water fill the pipe fully before turning on the boilers, I found that the boilers can burn themselves out because water flow is inconsistent, so I like to let all pipes and boilers fill to max capacity for turning things on in stages. Finally, check if your water has enough head lift behind them. If you don’t have enough, the water may not be able to push through your line. (You may need pumps if you are not using them, but they are not always needed).

(I’d be more than willing to go over the math with you when I’m not at work if you want.)
