The author presents the results of a series of tests conducted to determine the effect of the location of a venturi meter on its coefficient of discharge. These results are shown graphically together with sketches of the type of installations and venturi meters for which the coefficients were determined. The author shows mathematically and experimentally that for normal turbulence and shooting flow the coefficients are the same for low-ratio meters, but that for high-ratio meters the coefficient increases from that for shooting flow to the normal value in about 20 diameters of mixing lengths. |
