entering data in the start distance and stop distance cells. Enter a sprinkler number (from Column C of the Sprinkler worksheet) in order to analyze the effect of one sprinkler. This can be helpful to analyze the effect of an end gun. Start Distance (ft): CPED estimates the application depth and calculates the uniformity starting at this distance along the center pivot lateral. For compliance with the national practice standard, do not enter a distance greater than 250 feet. Center pivots have difficulty applying water uniformly along the first part of the center pivot lateral (close to the pivot point). The national NRCS standard allows the design of a center pivot to ignore the first 250 feet along the center pivot lateral for the uniformity calculations. This accounts for approximately 4.5 acres. Stop Distance (ft): CPED estimates the application depths and uniformity stopping at this distance of the lateral. This distance can be greater than the length of the lateral. Distance Increment (ft): CPED models the application depth at each of these distance increments. For example, entering 10 (feet) will instruct CPED to calculate the application depth every 10 feet along the lateral. Typical distance increments are 10 feet and 20 feet. Uniformity calculations may vary slightly with different distance increments. Minimum Depth (in): Simulated application depths less than the number entered here will be excluded from the uniformity and all other calculations. For example, this can be used to exclude data generated past the end of the lateral, as the irrigation application depth goes to 0. Travel Distance (ft): This is for linear move systems only. Enter the length of the field in the direction of the linear travel (i.e. how far the linear must move). System Parameters Type of Pressure Control: Choose from the options in the pulldown list: None Use this option when is no method to control the pressure of the system. An example of a method to control the pressure is the use of pressure regulators. Pressure Regulators Use this option when pressure regulators are used. Even if pressure regulators are entered on the sprinkler worksheet, if this option is not selected CPED will not recognize them. Fixed orifice
