Water flows in a horizontal pipeline at a steady flow rate of 0.03 m3 s-1. The pipeline terminates with a reducing bend that deflects the water upwards at an angle of 45 degrees, as shown in Figure QB2. The water issues into the atmosphere. The area of the pipe is 150 x 10-4 m2 and the area at the exit to the bend is 25 x 10-4 m2. The gauge pressure at the inlet to the bend is 73.9 kN...
