P3.43 Water at 20°C flows through a 5-cm-diameter pipe that has a 180° vertical bend, as in Fig. P3.43. The total length of pipe between flanges 1 and 2 is

75 cm. When the weight flow rate is 230 N/s, p¡ = 165 kPa and p2 Neglecting pipe weight, determine the total force that the flanges must withstand for this flow.134 kPa.
