Question
Problem 3. A Venturi tube is used to measure the water flow rate (Fig. 3). The wide section of the tube has a diameter D1 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? 10 cm, while the constriction has a diameter 13.56 g/cm³). Apply Bernoulli's equation to find the flow 2 cm Figure 3: 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. Figure not to scale.

Problem 4. An irrigation system consists of 5 parallel triangular-shaped swales (Fig. 4). The earthen swales are clean and recently completed, and its bed drops 1 ft per 200 ft. 1. Given the water depth h is 2 ft in the canal, calculate the total flow rate of the irrigation system using the Chézy equation and Manning's formula. 1 m. Suppose that the flow rate in the channel 2. The height of the swales are H = is increased by 50% due to a recent storm, are the swales deep enough such that the water does not spill over the top? H Figure 4: An irrigation system consists of 5 parallel triangular-shaped swales. The angle a = 45°. Figure not to scale.
