A pipe bends as shown in the diagram is carrying sea water with a steady flow rate of 2 m/s and held with two flanges. The diameter at the pipe is constant with 0.8 m. The bend has an angle of 45 and lies in a horizontal plane. The volume of sea water in the bend is 1.5 m, and the empty weight of the bend is 5 kN. Assume the fluid pressure is constant at 75 kpa along the horizontal line, (a) Find the force required to hold the bend in place. (5P) (b) Determine the angle of the resulting force acting on x,y plane (2P) 8 = 45
