The peak monthly demand for wheat as determined by using the Blaney-Criddle <br /> method was determined to be 4.11 inches for May, see Table 5-2. The volume of <br /> water required to meet that demand is estimated to be 4.84 inches during the month <br /> of May, assuming an irrigation efficiency of 85 percent (4.11 inches/0.85). This is <br /> equivalent to 49.2 acre-feet for a 122-acre center pivot (4.84 inches x 122 acres/12 <br /> inches/ft.). <br />2. The number of hours required to operate an irrigation well to satisfy the seasonal <br /> water requirement for wheat is determined by dividing the total volume, 1.06 acrefeet <br /> per acre (0.9 acre-feet per acre, presented in Table 5-2 divided by an irrigation <br /> efficiency of 85 percent). Based upon this seasonal requirement, a 122-acre pivot will <br /> require 129 acre-feet per season (1.06 ac. ft.lacre x 122 acres). <br /> <br />V-12 <br />
