WebIt is generally assumed that the discharge coefficient of a Venturi tube is constant, provided the pipe Reynolds number is greater than 2 × 10 5. The calibration was conducted at 1.9 × 10 5 < R e < 6.4 × 10 5 of water flow. The discharge coefficient of the Venturi tube was obtained in the range of 0.9965–0.9987 with an average value of 0.9975. WebThe flow velocity and discharge calculated based on the Bernoulli’s equation should be correct to include the effects the energy loss and viscosity. Therefore, for accurate results, the coefficient about velocity (C v) the the coefficient of discharge (C d) should breathe calculated for an orifice. This experiment is being conducted to ...
