In this article, I will describe prismatic channels and non-prismatic channels. These two channels are considered open channels. Let’s get started. First, we will know about prismatic channels. What are Prismatic Channels? Prismatic channels have a uniform cross-section throughout the channel length and constant bottom slope. Prismatic channels can be triangular, rectangular, parabolic, trapezoidal, or … Read more
California Bearing Ratio test or CBR is used to calculate the strength of the material for pavement design. CBR test is the test that was developed by the California state highway department of the USA for the determination of subgrade strength of highway and air-filled pavement. It is a penetration test. In this test, a … Read more
Blockboard has engineered compound plywood which comprises softwood stripes. These softwood stripes are joined edge to edge and then glued together under high pressure. The standard size of the blockboard is 2440 x 1220 x 30 millimeters but it is available in different sizes. Blockboard is used in furniture, articles that needed light-weight veneering, that … Read more
The reinforced concrete beam which is constructed on the ground level is known as the grade beam. Mostly it is used to connect pile caps in pile foundation. The functions of a grade beam are very different from a wall footing because a grade beam is designed for bending. A grade beam is normally a … Read more
Floor Space Index (FSI), is the ratio of the total floor area of a structure (Built-up area) to the total Plot area (land). Floor Space Index (FSI) is also known as Floor Area Ratio (FAR). This numeric value of the Floor Space Index addresses the total amount of area (on all floors) you can build … Read more
Wien’s Law, named after the German Physicist Wilhelm Wien, discloses to us that objects of various temperatures transmit spectra that top at various frequencies. More sizzling radiations transmit radiations of more limited frequency and henceforth they seem blue. Essentially, cooler radiations discharge radiations of longer frequency and thus they seem ruddy. In this short piece … Read more
There are 3 laws discovered by Kepler. These empirical laws are known as Kepler’s laws of planetary motion. The elliptical orbits of planets were represented by calculations of the orbit of Mars. From this, Kepler describes that different bodies in the Solar System, including those who are very away from the Sun, also have elliptical … Read more
Canal fall is a solid masonry structure that is made on the canal if the natural ground slope is steeper than the designed channel bed slope. If the difference in slope is little, a single fall can be made, but If it is higher then falls are made at regular intervals. Types of Canal Falls: … Read more
Silica fume or micro silica is an amorphous polymorph of silicon dioxide and silica. Silica fume is an ultrafine powder. It is a silicon and ferrosilicon alloy. Micro silica consists of spherical particles with an average particle diameter of 150 nm. It is a very reactive pozzolana due to its chemical and physical properties. When silica fume is used … Read more
The ratio of the effective length of a column (Le) and the least radius of gyration (r) about the axis under consideration are known as the Slenderness ratio. It is indicated by the “λ” (lambda). The slenderness ratio is called about the minor axis of cross-section and major axis of the cross-section. Effective slenderness ratio of the section … Read more
