Hi guys

I have a little problem.

I have to sort out the design for a pipe riser. Thing is I can't start to figure out what size of pipes I need until I know what sort of flow I want to maintain.

Now I know the inlet pressure into my system....2 bar. The first run of pipe is 3/4" which then branches off to 1/2"

I also know the distances that the pipes have to go. Basically how do I know what flow rate I'm going to get out of a tap given that the inlet pressure is 2 bar, I know the size of the internal pipes and the distance from the inlet to the tap.

All I need is the formula then I can go and get the flow rate. Then I can go and design my riser.

Cheers
