QUESTION
High flow water pressure system

I want to have a sprinkler system.

Total length of pipe 150 ft
Diameter of pipe - 1"
Maximum head height = 30 feet
Suction lift - 0 feet for submersible and maximum 10 feet for surface
My Requirement is - 400-600 ltr per minute water flow.
 
Now, my question is: If I attach open well submersible pump in this system of 1.5 to 2 Hp with inlet of 2" and outlet of 2" with flow rate of 600 ltr per mnt to 1" output pipe, which means the output diameter will reduced, then will the pump deliver same flow of 6000 ltr per mnt? Plz guide.
