Water spray bar design.
Water spray bar design.
(OP)
I am trying to design a water spray bar. I am going to use a 1" SS pipe that is 57" long and I am mounting 12 1/4" SS valves then misting nozzels (1.5 GPH each) to the valves.
My original plan was to feed the spray bar with a 1/2" SS pipe right from the center. but I am having a second thought about that and I am thinking of feeding from both ends to avoid turbulant flow and pressure reduction at the center of the spray bar. I am not sure which way to go.
Any help with that will be appreciated. please explain why which way is better than the other.
Water pressure is 40PSI, Total flow rate should be around 18GPH, water is 120 degrees.
Thanks,

We use spray bars for window and wall testing. Our output per nozzle is quite a bit higher than yours (5.0 gal/ft^2/hour or about 11 gal/hour for typical nozzle spacing), and we sometimes have to balance the nozzles, even though our spray racks are looped with water coming at the nozzles from at least two "directions".

These answers cleared a lot of things.
