NOTCHES AND WEIRs

Image
   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...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...
