In need of someone who understands these things better than me.
I'm looking to see what size pipe is needed for a filter to operate without being restricted so in other words how big the diameter of a pipe needs to be to allow a particular amount of litres per hour.
Am I correct to think I need to know the velocity of the water to calculate this?
Hopefully someone out there understands these things and can give me some guidance.
I have used the calculator below but I think I need the velocity to get the correct answer.

This is all to do with spraybar calculations; the general rule I was given was to match total area of holes in the spraybar to the diameter of the pipe BUT both the Fluval G3 and G6 have the same size pipes yet very different flow rates: 700 and 1000 litres per hour.
So this would mean if I followed the rule then my spraybar would have the same overall area of holes for both filters which I don't think is right and the overall area of holes I calculated is very different to the sprayar Fluval supply which is the same with both filters although it can restrict flow on the G6.
I look forward to someone with understanding to educate me and hopefully help me fill in the blanks.
Cheers
