(1) Water is flowing vertically from bottom to top in the pipeline shown in the figure. When the pressure difference between upstream side and downstream side across the contraction part was measured with a manometer, it showed the level difference of h. Answer each of the following questions. Ai is the cross-sectional area at the upsteam section of the pipeline and A2 (AI) is the cross-sectional area at the downstream section, and the density of water is pw, the liquid density in the manometer is pm, and the gravitational acceleration is g. Assume the uniform flow at each cross-section, and neglect any loss in the pipeline. (30 points) (1) Find the flow velocity at the downstream section of pipeline. (2) Find the flow rate in the pipeline. h Pmal
