Designing: How to design a Drip irrigation System

 Introduction: As drip irrigation is already introduced in  "introduction to drip irrigation" . This article aims to explain a general design for an efficient drip system. This  will involve some engineering concepts, fundamentals of fluid mechanics and mathematics. Considerations: Following steps are fundamental to design drip irrigation system for a given crop, area and water availability: • Survey of the area Find the total area that needs to be irrigated using the drip system. Then determine the topography and relative position to the highest point from the pumping unit. Determine the type of crop (vegetables and drip system are a perfect match) and find the power source, also, locate where the pumping system is located. Determine where Main lines, submain lines and lateral will be laid out. Refer to the image below.   • Water quality consideration Emitters in a drip system have very small openings and can be easily clogged by dust particles, salts and other soli...

Fluid Statics: Manometry

Manometry is the science of measuring pressure with the help of manometers , instruments that utilize columns of liquid. By analyzing the height of these liquid columns, we can determine the pressure being exerted. How Does it Work? Imagine a U-shaped tube partially filled with a liquid like mercury or water. One end of the tube is connected to the pressure source (the fluid whose pressure we want to measure), while the other end remains open to the atmosphere. Here's the magic: The applied pressure forces the liquid in the connected arm to rise. This movement creates an  imbalance  in the pressure between the two arms. Due to the fundamental principle that pressure equals the product of density, gravity, and height (P = ρgh), the height difference between the liquid columns signifies the pressure difference being measured. The simple formula to find pressure of fluid using a manometer is to draw a straight line across the U shape at same elevation as shown by the dotted line ...

Irrigation: Drip Irrigation Technology

Introduction: Drip Irrigation is the process of slow application (droplets) of available water on or below the soil surface as per the requirement of the crop. The first account of drip irrigation system is recorded in Germany in 1860. The drip irrigation as known today was introduced (or made mainstream) by an Israeli engineer Simcha Blass in 1930's. He noticed a tree near a leaking faucet was growing greener and healthier than the ones surrounding it.                                               Figure 1: A typical Drip Irrigation Field View He then founded a company in called Netafim  which is a giant in the industry of High Efficiency Irrigation Systems. Thus, irrigation and agriculture was never the same and was revolutionized by Drip irrigation technology. Components of A drip Irrigation System: • Head Unit: Head unit consists of prime mover (motor or engine), w...
