the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Effect of Height of Sharp-Crested Weir on Discharge Coefficient
Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purp...

متن کاملِِDischarge Coefficient in Oblique Side Weirs
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...
متن کاملEffect of Deflector and Aeration On the Discharge Coefficient of Submerged Flow of Morning Glory Spillways
Spillways are responsible for draining floods in dams. However, morning glory spillways are considered as free spillway type. In floods, a submerged flow is formed in their crest. This factor leads to severe pressure fluctuations in the shaft, suction and vibration of the structure and also reduces the spillway efficiency. Insufficient knowledge of the hydraulics of the submerged flow will be a...
