Abstract
Weirs and notches are efficient devices for measuring flow rates. Banks of slit weirs forming multislit weirs allow both precise discharge measurements in a very large range of flow rates and permit a good flow regulation. V-shaped weirs are traditionally used as precise laboratory flow measuring devices, especially in the low discharge ranges. In the current investigation, the method of images was used to form the V-shaped multislit weir system to allow measurement and regulation of flows in a large range of flows that includes very low flow rates. Experimental studies were conducted to determine the discharge coefficients of V-shaped multislit weirs over a wide range of weir Reynolds numbers. The study provided a single relation between the weir discharge coefficient and the weir Reynolds number for both the rectangular and V-shaped multislit weir systems.
