2. The pipe configuration below represents an elbow pipe (laying horizontally on a floor) in which water flows. D160 mn -999 m3 12-03mB Lİ 0.75m A+ 01-300 mm Neglecting all atmospheric pressure effects and using as gravity g-9.81 m/s, answer the following questions (a) Draw a suitable control volume, and briefly motivate your choice. (b) Compute the anchoring force in the y-direction necessary to hold the pipe in place. c) Compute the anchoring force in the r-direction necessary to hold the pipe in place(d) Assuming that force resulting from the water flowing in the system passes through point A, and that the system is pinned at the location B, what is the torque necessary to hold the system in place? (e) The static friction coefficient at the interface pipe-floor is s 0.5, so that the maximum friction force is FmaWss, where W, is the weight of the system. The density of stainless steel is p 7500 kg/m3. Is the system going to stay in place on its own? Explain and list your assumptions. (f) How the z-component of the resulting force scales with respect to V, D, D (g) If the flow rate must be kept constant, what is the easiest modification to the system u anprt to mee Explain

    A 10 cm, 90° elbow in a horizontal pipe directs flow of water upward at a rate of 40 kg/s. The elevation difference between centers of the pipe exit and the inlet to the elbow is 50 cm. The weight of the elbow and water can be neglected. The momentum flux correction factor is 1.03 at both elbow inlet and outlet. Find: a. gauge pressure at the inlet to the elbow in kPa b. magnitude of anchoring force need to...

    4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...
