  4. ation of discharge in case of triangular notch

Hence for a rectangular notch the coefficient of discharge is not actually a constant but is a function of the head over the notch. (ii) When the discharge rate is small a triangular notch provides a greater head than the rectangular notch. Hence head measurement can be done more accurately over the triangular notch than over the rectangular notch Advantage of triangular weir over rectangular weir: A triangular weir is preferred to a rectangular weir due to following reason. (1) The expression for discharge for a right angled V- notch or weir is very simple. (2) For measuring low discharge, a triangular weir gives more accurate results than a rectangular weir 9.2. Calculations. The following dimensions from the equipment can be used in the appropriate calculations: - width of rectangular notch (b) = 0.03 m- angle of V-notch = 90°Calculate discharge (Q) and head (h) for each experiment, and record them in the Result Tables.For calculation purposes, the depth of the water above the weir is the difference between each water level reading and the.

Advantage of Triangular Notch Over Rectangular Notch

(iii) Tire 90° Triangular Notch Weir: Triangular notch weir is formed by the notch sloping outward from the vertical at a 45° angle and meeting at a point in the centre of the bulkhead and has no crest length (Fig. 3.16). This weir gives most accurate results when measuring small discharge of less than 1 sec-ft. to a maximum of 10 sec-ft In its simplest form, a weir consists of a wall of timber, metal or concrete with an opening with fixed dimensions cut in its edge (see Fig. 87). The opening, called a notch, may be rectangular, trapezoidal or triangular. Fig. 87. Some examples of weirs . A RECTANGULAR WEIR. A TRIANGULAR WEIR. A TRAPEZOIDAL WEIR. b. Parshall flume The discharge coefficient is a dimensionless number used to characterise the flow and pressure loss behaviour of nozzles and orifices in fluid systems. Orifices and nozzles are typically used to deliberately reduce pressure, restrict flow or to measure flow rate. This article gives typical values of the discharge coefficient for common orifice and nozzle designs A two-story building locally named Carbonhaus on the campus of Technical University in Dresden, Germany is under construction which will be the first building in the world built entirely on Carbon Reinforced Concrete. The building has a covered area of 2200 Square feet and will be completed with a budget of 5 Million Euros (US$5.63 million)

The two laboratories sessions are: 1. Impact of jets on various shaped surfaces - a jet of water is fired at a target and is deflected in various directions. This is an example of the application of the momentum equation. 2. The rectangular weir - the weir is used as a flow measuring device. Its accuracy is investigated Flumes are more adaptable in their sizing, configurations, and installation, while weirs, on channels capable of developing a proper weir pools, tend to be less expensive. Of the two, weirs show greater laboratory accuracy (+/-2-5%) than flumes (+/-2-6%), although in practice and under field conditions, the total system accuracies tend to be.

Distillation Column Tray Selection & Sizing - 1. Once the process design stage ends, the equipment design begins. This stage of design converts process requirements into actual hardware. One of the most prominent hardwares used for mass transfer is tray. Tray columns are widely used in various types of mass transfer operations (4.21)]. For a rectangular weir n = 1.5. The various flow measuring structures can be broadly considered under three categories: Thin-plate structures are usually made from a vertically set metal plate. The V-notch, rectangular full width and contracted notches are typical examples under this category The orifice, nozzle and venturi flow rate meters use the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow. In a flow metering device based on the Bernoulli Equation the downstream pressure after an obstruction will be lower than the upstream pressure before This book on Agricultural Engineering integrates post harvest engineering, protected cultivation, land surveying and soil-water conservation engineering. The book organizes the scattered information and provides better practical skills to the students and to serve as a practical reference book for the undergraduate students of Agricultural Science, Horticulture and Agricultural Engineering.

EXPERIMENTAL PROCEDURE 1. Fit the rectangular notch plate to the weir plate carrier which is bonded into the free end of the molded channel in the top of the hydraulics bench V-Notch. In this case, the notch is V in shape. Depth of water above the bottom of the V is called head (H). The V-notch design causes small changes in discharge hence causing a large change in depth and thus allowing more accurate measurement than with a rectangular notch. Stepped notch

Weirs are structures consisting of an obstruction such as a dam or bulkhead placed across the open channel with a specially shaped opening or notch. The flow rate over a weir is a function of the head on the weir. Common weir constructions are the rectangular weir, the triangular or v-notch weir, and the broad-crested weir Why v notch gives more accurate result than rectangular notch? A triangular notch gives more accurate results for low discharges than rectangular notch and the same triangular notch can measure a wide range of flows accurately. 6.
