An orifice is an opening, of any size or shape, in a pipe or at the bottom or side wall of a container (water tank, reservoir, etc.), through which fluid is discharged. … WebJul 21, 2024 · Calculate velocity by dividing the length of the orifice by the number of seconds the object took to reach the bottom of the orifice. So, for a length of 20 meters …
Webdischarge coefficients of an orifice as a function of Reynolds number were determined by measuring the flow rate and pressure drop across the orifice. The discharge coefficient was calculated to be 0.920 at a Reynolds number of 12700, 0.926 at a Reynolds number of 18500, and 0.935 at a Reynolds number of 21600. These values were about 47%
