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...

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: Archimedes Principle Made Simple

The Story of Archimedes' Principle Thousands of years ago in 250 B.C a man named Archimedes in Greece ran naked into the street shouting at the top his lungs eureka!. Such enthusiasm is justified when you just discovered an experimental method to find the gold content in the crown of king of Syracuse (or else get Zapped!). The story goes such that the king suspected some blacksmith had short changed him by making him a crown of alloyed gold (Blasphemy!). So, he consulted Archimedes a wise and a great scientific mind of that time (remember it is Greece) to check if such is the case. The Approach to the problem Most people would approach this problem by taking into the account the weight of crown and try to compare it to the weight of a crown made by pure gold. But lets say the forger was very clever and made sure that this crown of alloyed gold was to weigh the same in air compared to a crown made with pure gold (say the king already has). This now complicates the problem (for that...
