摘要：In open channel flow measurement, weirs and flumes are used to produce known repeatablecharacteristics in the process of stream. Weirs, flumes and other devices develop a liquid head that is used to measurethe flow rate. Weirs also give engineers as well as hydrologist a simple method of measuring the rate of fluid flow insmall and medium sized stream or in industrial discharge locations.One such type of the parabolic weir is studied here. In this type of weir the discharge equation was having aflow depth exponent as a whole number. A Parabolic weir profile gave the simplified discharge equation with two asthe flow depth exponent. In this project the parabolic weir with weir angles 30°, 45°, 60° were designed and fabricated.Various head measurements are taken in the flume at various equidistant places. The coefficients of discharge weremeasured.
