Toro Precision Chip Sprinklers and Design Question

Using Schedule 40, Source is 40PSI I am using...

[align=-webkit-auto]15-H 90, 15' X 2 = 0.58 X 2 = 1.16GPM
10-F 360 10' X 1 = 1.04 X 1 = 1.04 GPM
10-H 180 10' x 1 = 0.52 X 1 = 0.52 GPM
15-H 180 15' x 2 = 1.17 x 2 = 2.34GPM

Total 6 Sprinklers

This circuit which is L shaped, on the bottom leg of the L, I wish to place the 1 10' 360 degree Toro Precision sprinkler listed above, on the Supply Pipe.

The design shapes I have seen show that you ought not to put sprinklers on supply llines.

Granted this is only 1 Sprinkler right on the Supply line, Max Supply for Schedule 40 is 8GPM.

Will this not work at all? What do you think? This is just a residential front lawn.

What do you mean by supply line? All heads need to be installed after a valve, no?

I'm a little confused my self.
Anything downstream of the control valve should be fair game.
Rough piping terminology : main to zone valves, lateral after valves.
So you would still be on a lateral, correct?
