Vertical Gardening Supplies

there is 26 feet of water head in a pipe and a rotating nozzle set at 90degrees apart around the circumference and nozzles tangentially fitted (like a garden sprinkler). The water is conveyed to the nozzles by 4 pipes branching from the central pipe.The water head is maintained at 26 feet by a constant supply at the top of the vertical pipe. What is the thrust at the nozzle end and the rotational speed and the centrifugal force developed at the end of the nozzle?
