  1.       Main canal The main canal takes off directly from a river or reservoir. It carries water in large amounts to feed the branch and distributaries canals. Due to conveying of very high discharge through the main canal it is not recommended to do direct irrigation from it. 2.       Branch Canal   The branch canal takes off from main canals at regular intervals. These canals supply water to major and minor distributor’s canals.   The discharge of the branch canal is generally over 5 m3 /sec. 3.       Major Distributary Canal   Major distributary canal takes off from the branch canal or in some cases from the main canal. They supply water to minor distributaries and field channels.   A canal is said to be major distributary when its discharge lies between 0.25 to 5 m3 /sec.     Minor Distributary Canal Minor distributary canal takes off from major distributaries and sometim...

"Multi-disciplinary collaboration with BIM" refers to the process of integrating and coordinating the work of different design disciplines, like architecture, structural engineering, mechanical, electrical, and plumbing (MEP), within a single Building Information Model (BIM) to facilitate seamless communication and collaboration between all project stakeholders, minimizing design conflicts and improving project efficiency throughout the construction lifecycle.  Key aspects of multi-disciplinary BIM collaboration: Centralized model: All disciplines create and access their design elements within a single 3D BIM model, allowing everyone to see the project holistically and identify potential clashes early on.  Clash detection: BIM software can automatically detect conflicts between different design elements from various disciplines, such as an HVAC duct intersecting a structural beam, enabling proactive issue resolution.  Improved communication: By working on a shared m...

   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

  What is an Orifice Meter? The orifice meter is a type of flow meter used to measure the flow rate of fluids (liquids or gases) based on the principle of differential  pressure  measurement.    Construction of Orifice Meter Inlet Section:  The fluid from one end of the pipe enters through this section. The diameter of the section depends on the flow to be measured. Orifice Plate:  A device used for measuring flow rate, lowering pressure, or restricting flow is called an orifice plate . These plates are usually thin with holes that are installed in pipes. U-Tube Manometer:  A manometer monitors the pressure of fluids. A U-tube column filled with mercury serves as the pressure reading display in a U-tube manometer. One end of it is installed before the orifice plate and the other end is installed after it. Outlet Section : This is the section w...

Venturi meters are instruments for fluid flow   measurement. It has a converging section that gives an increase in the flow velocity with a corresponding drop in pressure from which the flow rate can be calculated.  The reduction in the fluid pressure that occurs when a fluid moves through a constricted passage is known as the Venturi effect.  Venturi meters are widely used wherever there is a need for fluid flow measurement, specifically in water, chemical, and oil industries.  Depending on the application and size requirements, industrial venturi meters are constructed in various forms.  These versatile instruments are known for longevity, long performance, and reliability. In this article, we will discuss about the following: Definition of Venturimeter Venturimeter Diagram and Parts Working Principle of Venturi meter Co-efficient of Discharge for Venturimeter. What is a Venturimeter? Venturimeter Definition Venturimeter is a  type of flowmeter  that...
