Can you calculate how pipe diameter affects flow rate?
What is needed to calculate? Flow rate (gpm) and pressure?
As a guide how does the flow rate decrease as length increases? Does pipe material make a difference (i.e copper / speedfit)
i.e if water pressure is say 2bar, flow into pipe is 1gpm what would be flow be at the end of say (assuming no elbows, etc)
