Abstract: A Venturi flume is a device used to calculate the rate of flow of a liquid in considerable amounts. It is based on the Venturi effect, for which it is named.A Venturi flume is a flume with a contracted region situated in its center which, due to the Venturi effect, results in a decrease of fluid pressure at the center of the constriction. By comparing the fluid pressure at the center of the flume with that earlier in the device, the rate of flow can be measured. In this study, various width ratio of transitions have been made under different discharges for optimising the width at transition to avoid supercritical condition . From the experiment it has been found for various discharges that the width ratio of 0.36 when the flow becomes critical. In the various width ratio it has been found for width ratio 0.36 the flow at the throat section is just critical and if we further decrease the flow may become critical. For high discharges ,water surface profile increses with the width ratio.But for the low the discharges the water surface for the 0.36 and 0.4 closesly move. The Froude number is found to be increasing when the discharge is increasing. But it is interesting to see that the width ratio is decreasing but the Froude number at the throat section is going to critical.
