Problem 5. A Venturi tube is used to measure the water flow rate (Fig. 5). The widesection of the tube has a diameter D1 = 8 cm, while the constriction has a diameter D24 cm. The pressure difference between the wide section and the constriction is measuredby a mercury manometer (PHgrate. State all your assumptions. Calculate the Reynolds number associated with water flowat the constriction. Is your assumption justified?13.56 g/cm³). Apply Bernoulli's equation to find the flow2 cmFigure 5: A Venturi tube is used to gauge the water (blue) flow rate.
