Now, enter the values appropriately and accordingly for the parameters as required by the Field Irrigation Requirement (FIR) is 72 and Water Conveyance Efficiency (η c) is 12.Īs you can see from the screenshot above, Nickzom Calculator– The Calculator Encyclopedia solves for the gross irrigation requirement and presents the formula, workings and steps too. The screenshot below displays the page or activity to enter your values, to get the answer for the gross irrigation requirement according to the respective parameters which is the Field Irrigation Requirement (FIR) and Water Conveyance Efficiency (η c). Now, Click on Gross Irrigation Requirement under Irrigation Water Requirement Now, Click on Irrigation Water Requirement under Agricultural Once, you have obtained the calculator encyclopedia app, proceed to the Calculator Map, then click on Agricultural under Engineering. It is required to determine the water conveyance efficiency, water application efficiency, water storage efficiency, and water distribution efficiency. The available moisture-holding capacity of the soil is 20 cm per metre depth of soil. ![]() To get access to the professional version via web, you need to register and subscribe for NGN 2,000 per annum to have utter access to all functionalities. The depth of water penetration varied linearly from 1.7 m at the head end of the field to 1.1 m at the tail end. You can get this app via any of these means: Introduction Water Conveyance Efficiency - Irrigation Efficiencies - GATE Irrigation Ekeeda GATE & ESE 22.9K subscribers Subscribe 397 views 1 year ago Irrigation - CE GATE & ESE Subject. To get the answer and workings of the gross irrigation requirement using the Nickzom Calculator – The Calculator Encyclopedia. First, you need to obtain the app. Nickzom Calculator – The Calculator Encyclopedia is capable of calculating the gross irrigation requirement. Therefore, the water conveyance efficiency is 4. Given that the gross irrigation requirement is 5 and the field irrigation requirement is 20. Therefore, the field irrigation requirement is 140.Ĭalculating the Water Conveyance Efficiency when the Gross Irrigation Requirement and the Field Irrigation Requirement is Given. ![]() ![]() Therefore, the gross irrigation requirement is 6.Ĭalculating the Field Irrigation Requirement when the Gross Irrigation Requirement and the Water Conveyance Efficiency is Given.įind the field irrigation requirement when the gross irrigation requirement is 10 and the water conveyance efficiency is 14. The formula for calculating gross irrigation requirement įind the gross irrigation requirement when the field irrigation requirement is 72 and the water conveyance efficiency is 12. To compute for gross irrigation requirement, two essential parameters are needed and these parameters are Field Irrigation Requirement (FIR) and Water Conveyance Efficiency (η c). A 50ft long and straight earthen channel was. FIR GIR x c FIR 10 x 14 FIR 140 Therefore, the field irrigation requirement is 140. The image above represents gross irrigation requirement. The purpose of this study was to determine the conveyance losses of irrigation water through earthen channel.
