pipe and friction loss

I'm installing a sprinkler system using 1" poly pipe. I'm planning to run all pipes from a valve manifold in the back of the house. The farthest point in the front yard is about 150' from the valve. My water flow is 20gpm, and the water demand of the sprinklers on this valve is 15 gpm. Will there be enough water to meet this demand, given the friction loss from this long span of pipe?

without pressures being known, you can only guess

Get a pressure reading for the system then you will be able to tell

More then likely it should be fine though.. Maybe install smaller nozzles to reduce your zones gpm
