A liquid (? = 1.65 g/cm3) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm2, the flow speed is 249 cm/s, and the pressure is 1.20 105 Pa. In the second section, the cross-sectional area is 4.00 cm2. (image) The flow within a horizontal tube is depicted by five lines. The tube extends from left to right, with the left end wider than the right end. The five lines start at the left end, go horizontally to the right, curve slightly toward the center of the tube such that all five lines come closer together, and again go horizontally to the right to exit at the right end. Arrows on the lines point to the right to represent the direction of flow. (a) Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.) m/s The answer is 6.225 m/s. (b) Calculate the smaller section's pressure.
