Problem Statement A Reducing Elbow Is Used To Deflect Water Flow By An Angle Of 45 From The Flow Direction The Elbow 1 (96.69 KiB) Viewed 55 times

Problem Statement: A reducing elbow is used to deflect water flow by an angle of 45° from the flow direction. The elbow discharges water into atmosphere. The elevation difference between the base and spout of the elbow is only 0.04 cm and hence the potential energy between both points can be neglected, and thus atmospheric pressure is all around. The mass of the elbow and the water is taken to be 50 kg. The frictional force (Ft) is 10 N with direction as shown in the diagram. Determine the following: • Consider p = 1000 kg/m3 and atmospheric pressure to be 101 kPa • What are the valid assumptions (select all valid choices)? • What is the water velocity magnitude at the inlet (V)? • What is the water velocity magnitude at the outlet (V)? • What is the horizontal force (Ry) that must be applied to hold the elbow in place? • What is the vertical force (Ry) that must be applied to hold the elbow in place?
