Mini Jet Sprayer head recommendations

Hello,

I use an aeroponic/nft system and want to upgrade to a bit larger setup. I wanted to know if anyone knew how to calculate the required GPH needed for a water pump with a certain number of feet and 360 degree EZ clone sprayers.

Example,

I intend to use about roughly 28 feet of 1/4" schedule 40 PVC with a total of 30 sprayer heads (10, 360 degree heads and 20, 180 degree heads). The actual "run" of each of the supply lines will be 8 feet in length with 10 sprayer heads (about 9.5" apart on center). The remaining 3 feet is the connection from the pump into a t configuration which connects to the 3 supply lines.

The sprayer heads are rated at:
.15 to .63GPM
15-35PSI working pressure

So what size pump do I need? Also, how would this change if I went from 1/4" to 1/2". I realize it would drop pressure but how would you calculate for the 1/2 vs. the 1/4? Please, dont reply with "just get the biggest one you can afford". I would like to calculate this so I at last have a close range as not to stress the pump and shorten longevity.

TIA

i wouldnt go 1/2" stick with the 1/4" PVC to gain more pressure, my table runs a Aqua One 105 Pump rated at 2200 litres an hour, to get good pressure with the 1/4", anything above 2500 litres an hour will be perfect. good luck.

I use a high head aquarium pump. Fatman turned me on to this before he got tossed. I use an iwaki pump and dago sprayers. Also I use a solenoid valve to keep the pump running 24/7 but only spraying 1 min on 4min off.

THANKS GOES OUT TO SOG FOR THIS INFO....

let me know how this turns out ...I too am going to run full 8 foot long 4"x4" tubes in the near future.

I was burnt when I wrote my last post. I have hago misters and you can use danfoss as well.
