Question: b the bend in the tube is shown as rounded...

Question details

b) The bend in the tube is shown as rounded. Biscuss how the answer to part a might change if the bend were a right angle rather than rounded. c) Estimate the drag on the tube. (24%) Water at 18 C enters the reducing elbow shown at 200 kPa gage and diseharges to the atmosphere. The upstream inside pipe diameter is 0.3 m and the diameter at the discharge is 0.1 m. The elbow lies in a horizontal plane and the flow may be assumed frictionless. Calculate the x-direction and y-direction forces necessary to hold the elbow stationary. No velocities are given. 40
