Unformatted text preview: to estimate flow rate, clear debris, defend against dogs/rattlesnakes, etc Efficiency (Multiple Choice) 11. A crop has had 3" of ET since the last irrigation. This depletion is uniform across the whole field. This is an actual field with a real irrigation system in it. The system is SDI (s ubsurface drip irrigation), assum ing no evaporation loss, no spray , nor runoff losses. Exactly 3" is applied to the field. What is the Efficiency? a) 100% b) Less than 100% c) Greater than 100% d) You can't tell, with the information that is given. 12. Which one of the following is impossible to achieve for practical irrigation of a field? a) The Efficiency is greater than the (DU x 100) on the same field b) Underirrigation simultaneously with a high Efficiency c) d) The Efficiency i s greater than 100%. The (DU x 100) is greater than the Efficiency...
