I'm designing my gardens irrigation system. If one nozzle needs 4bar, then will 2 nozzles use 8?

so i'd need 8 bar pumps to run them both, correct?

I've been doing this for 30 years and have no idea what you guys are talking about. "4bar", what does that mean? Pipe sizing is velocity X length equals friction loss. Use a gpm chart to size and nozzle.
Reply:One bar equals 14.5 psi. and is irrelevant to to your irrigation system, just use the standard nozzles all round and don't complicate things.
Reply:no, what is the pressure out put on the 4bar, if it is over 50 PSI then you are ok if not seperate 4 bar nozzles are needed
