Unformatted text preview: your first step in solving these problems. 5.1 9 Water flows through a horizontal pipe similar to the pipe in DL. It enters the pipe at point (1), then leaves the pipe at point (2), which is open to the atmosphere. The height of the water in each vertical column is shown at right. Now suppose that the length of this pipe is doubled. The pressure at point (1) is the same as before. Point (2) is still open to the atmosphere. Water is again allowed to flow from point (1) to point (2). (a) We find the flow rate in the longer pipe is smaller than the flow rate in the shorter pipe. Explain why this happens. By what factor would the flow of water through this pipe decrease? Explain your answer and show your reasoning. (b) Fill in the water levels in each of the vertical columns in the pipe whose length has been doubled, in the diagram below. Be clear and accurate in drawing each water level. 1 flow 2 open to air 1 flow 2 open to air Side Views showing elevations A B C...
