Calculates "scheduling coefficient", run-time <br />multiplier based on efficiency of the sprinkler performance. For single-leg <br />tests, assumes symmetrical performance over the arc of the sprinkler. <br /> <br />STRENG'rIlS: <br />tested. <br /> <br />Any number of spacings can be done once the sprinkler has been <br /> <br />WEAKNESSES: Only applicable to fixed, repeating spacing designs. <br /> <br />INPUT REQUIREMENTS: Lateral and sprinkler head spacings. <br /> <br />OUTPUT PRODUCED: "Densogram" - a graphical image of the water application over <br />the overlapped area. Efficiency coefficients, CU, DU, and scheduling <br />coefficients. Sensitivity analysis for scheduling coefficient based on a 1\, 2\, <br />5\, and 10\ window size and the single driest catchment. The window size is <br />based on the percentage of the overlapped area. The scheduling is a run-time <br />multiplier - it tells how much longer the system must run to get enough water to <br />the dry 'window'. <br /> <br />1-16 <br />
