Problem 2 8 kg/s 3 2. Water (density of 1000 kg/m3) is flowing into and discharging from a pipe U-section with a secondary discharge section normal to the return flow. The diameters at points 1, 2, and 3 are 5cm, 10cm, and 3cm respectively. Determine net Ex and Fy forces at the two flanges. Assume the weight of the u-section of pipe and the water in it is negligible. 22 kg/s FRZ 1 FRU Rx 30 kg/s
