Problem 5. A Venturi tube is used to measure the water flow rate (Fig. 5). The wide section of the tube has a diameter D1 = 8 cm, while the constriction has a diameter D2 4 cm. The pressure difference between the wide section and the constriction is measured by a mercury manometer (PHg rate. State all your assumptions. Calculate the Reynolds number associated with water flow at the constriction. Is your assumption justified? 13.56 g/cm³). Apply Bernoulli's equation to find the flow 2 cm Figure 5: A Venturi tube is used to gauge the water (blue) flow rate. The pressure difference in the Venturi tube is measured by a mercury (orange) manometer.
