Rotor basics help
Last year I used Toro for my backyard install of all spray heads. This year I'm planing to use rotors such as the Toro Multistream PRN due to a significant slope in my design for the front. Toro.com and customer service could not find any performance charts!! So I check Rainbird, printed a pefformance chart for their 12SA and I think I understand it based on all the reading I've been doing. Call Rainbird and they said they are busy try calling another time.
So, per the Rainbird chart, a full circle 360 degree rotor at 35 psi gives a radius of 16 feet and 1.73 psi. If I use the radius reduction (I know to try not to) the gpm stays at 1.73. Am I correct?
EDIT: I found a picture of the Toro Multistream - for a full circle 360 degree, Label has 35 psi - 19 feet radius and 2.35 gpm. So am I correct that I should be able to space them 19 feet apart expect 2.35 gpm useage?
