Velocity ___9. Volume ___10. Head a. Weir with trapezoidal shape b. Elevation of water surface from a reference point (such as the crest of a weir) c. ____ = velocity x area d. can be roughly estimated with an orange, tape measure, and stop watch e. Critical flow device with small head loss. The preferred device for canal measurement. (hint - rhymes with Google). f. Can be determined by weighing a quantity of water or using a container with known dimensions (like a 5-gallon bucket). g. Biggest source of errors with weirs. Can be adjusted by using the “run up” value on a weir stick instead of using a staff gage in a still. h. ____ = V 2 /64.4 i. Equation for flow: Q = C x A x H 0.5 j. simple device used on checks to estimate flow

Unformatted text preview: 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 (subsurface drip irrigation), assuming 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) The (DU x 100) is greater than the Efficiency d) The Efficiency is greater than 100%....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
