Effects of Pump Selection and Terrain on Center Pivot Performance
ABSTRACT NONDIMENSIONAL curves to represent the performance of 125 centrifugal and turbine pumps were developed. The James Center Pivot simulation model was modified and used with these curves to examine the effect of pump type and size, and nine terrains on the water applied, energy use, uniformity and adequacy of irrigation of center pivot systems with different sprinkler types. Fixed nozzle and constant discharge nozzle impact sprinklers were considered.
