Furthest Nozzel from mistking

You are thinking wrong.

There is no limit because its a membrane pump with a sealed tube end. The pressure at the nearest nozzle, is the same as the farthest. If you had 300ft of line the first nozzle would still spray just as well as the last.

I dont have the math to calculate the surface tension and friction of 1/4" tubing to figure out the required pressure drop needed in order to reduce the gallons per min of the nozzle.
