Micro Irrigation Engineer Interview Questions and Answers

Peak water requirement can be calculated by considering crop evapotranspiration, crop coefficient, and effective rainfall.

• Calculate crop evapotranspiration using FAO Penman-Monteith equation

• Determine crop coefficient based on crop type and growth stage

• Consider effective rainfall to adjust peak water requirement

• Peak water requirement = Crop evapotranspiration x Crop coefficient + Effective rainfall

To draw a polygon, you need to connect multiple points with straight lines to form a closed shape.

• Identify the points that will be the vertices of the polygon

• Connect the points with straight lines in the order of the vertices

• Ensure that the lines do not intersect within the polygon

• Close the shape by connecting the last point to the first point

• Label the vertices if necessary for reference

LPH can be calculated by dividing the total volume of water delivered by the total time taken to deliver that volume.

• Calculate the total volume of water delivered in liters

• Calculate the total time taken to deliver that volume in hours

• Divide the total volume by the total time to get liters per hour (lph)

NRV stands for Non-Return Valve, a device used to prevent backflow of water in a micro irrigation system.

• NRV is a mechanical device that allows water to flow in one direction only.

• It is commonly used in micro irrigation systems to prevent water from flowing back into the main water supply.

• NRVs are essential for maintaining the efficiency and effectiveness of a micro irrigation system.
