Center pivot irrigation systems are the most common system type in Kansas for a variety of factors – one of which is the ability to deliver a uniform depth of water application for a variety of crops and field conditions. Table 1 lists typical hydraulic drive center pivot oil pump horsepower, tire size, and end tower travel speed. Now that you know the flow rate, use the following formula to calculate the acre-feet of water that was pumped: Volume pumped = (hours of operation) x (gallons per minute) / 5,430 For example, say your center pivot ran for 895 hours Center Pivot Nozzle Package Uniformity Measurement Nozzle package uniformity is a measurement of how close to the desired application depth each location along the pivot lateral receives. 16. To change worn sprinklers and nozzles. To install the program, run SETUP.exe from the Pivnoz directory. Field Measurements 1. 32 total. As three generation farm family who has owned and operated center pivot for years . 5. Pivot Full Rotation Time: The time that it takes for a 360 degree rotation of a center pivot. to your center pivot. 14 to 16 m from the beginning at the center pivot to the end of the center pivot radial line. 3. The pipe line (lateral) is supported by steel frameworks (towers) spaced along the lateral. This can be obtained from the center pivot sprinkler chart. Learn how pivot irrigation can be a smarter and more cost-effective way to irrigate a variety of key crops around the world, including corn, soybeans, potatoes, biofuels and more. Pivot Charts in Excel are one of the easiest and best ways to visualize your data. In addition, the operation of the pivot along with proper tillage practices will affect the amount of runoff from the field. However, in western Kansas, almost 60 per cent of the nozzle packages are mounted at 4 foot or less above the ground agriculture engineering. Flows: 0.27 to 21.18 gpm (61 to 4811 L/hr) Pressures: 6 to 20 psi (0.41 to 1.38 bar) Growers trust Valley center pivots to last for decades, and it’s why Valley remains #1. This example shows the minimum water supply rate for a center pivot equipped with high pressure impact sprinklers should be approximately 772 gallons per minute (656/0.85).
