The smooth flow to and over the weir is essential to the determination of accurate rates of flow since the distribution of velocities in the approach flow has a definite influence on the discharge over the weir. WebThe goal of the experiment was to observe and calculate the experimental and theoretical flow rate and the experimental and theoretical discharge coefficient. 2 Introduction. For the experiment, two separate weirs were used: a Rectangular weir and a V-Notch/Triangular weir. Each weir was recorded at different water levels.

WebIt doesn't matter how thick the weir is except where water flows over the weir through the "V." The weir should be between 0.03 and 0.08 inches (0.8 to 2 mm) thick in the V.
