Calculating Head Pressure

[RealFish]

How do you calculate head pressure when you have manifold feeding multiple outlets. For instance, I'm potentially feeding a 200 gallon display tank with the outlet 15' higher than the pump. I'm also feeding a 60 gallon frank tag and a 30 gallon quaurantine tank about 3-4' higher than the sump.

I get the basic calculation, but not sure about when you have multiples.

Calculate the tallest run with the calculator in the home page. The others are ignored for the most part.

Thanks for the reply, that is what I figured. Add up the friction loss plus the actual height. I found a table. I think the friction loss for the other two outlets added about 1.5' together.
