Water flows inside a solid cylindrical pipe, which narrows as it goes up to a height h (see diagram below). The lower horizontal section has circular cross-sectional diameter d, whereas the upper horizontal section has diameter d/2. Let us denote A to be a point at the lower horizontal section and B to be a point at the upper horizontal section. The flow speed at A and B is uд and u, respectively. The pressure at A and B is PA and PB, respectively. РА UA Oom Ja d d/21 1 UB h (a) Assuming water to be incompressible, show that the flow speed at B is four times the flow speed at A. (b) Use Bernoulli's equation to find the drop in the water pressure from A to B. Express the result in terms of h, uд, the density of water p, and the acceleration of gravity g. (c) Above certain critical height h, vapour bubbles start to appear at the top horizontal section, which hinders water flow through the pipe. Explain why this happens.
Question 1: Water is expelled by a jet to the environment (i.e. the water flow is surrounded by atmospheric pressure). To change the direction of the water flow, this enters to a curved pipe as show in the figure (top view perspective). Calculate the forces exerted by the flow to the pipe in x and y direction (both horizontal). Use a water density of 1000 kg/m³, Q=1 m³/s, diameter d-0.3 m. Follow the 4 steps explained in the lectures and state your assumptions clearly. 30 Question 2: Repeat question 1 but change the curvature from 30 degrees to 90 degrees. How the forces change? 90
