Abstract
Venturi meter is a device used to measure the discharge of the flow of fluids in closed conduit. This device works on Bernoulli’s principle which states, “An increase in the speed of the fluid particle occurs when simultaneously with the decrease in pressure or decrease in fluid’s potential energy.” It consists of a converging section, a throat and a diverging section. Velocity increases with the decrease in the cross-sectional area and pressure. In this paper, the variations in pressure due to various bends applied after the diverging portion is depicted and is compared with the formal venturi meter mounted into a straight pipe. The diameter of the pipe is taken as 20 mm, converging angle is 11°, diverging angle is 6°, length and diameter of the throat portion are 20 mm and 10 mm. The results indicated the shape, size, and orientation of the pipe after the venturi meter. These parameters affect the performance of the venturi meter in the calculation of the coefficient of discharge. A detailed analysis was carried by computational fluid analysis by ANSYS software to know the pressure variations along the venturi meter, and also the velocity vectors along the length of the pipe.
