All the pipes are made of cast iron. The 5-cm pipe consist of three 90°. Here’s the best way to solve it. Determine the flow rate in the system in cubic meters per second by converting the given flow rate from cubic meters per hour.

Water at 20°C flows through a 5-cm-diameter pipe that has a 180° vertical bend, as shown in the figure below. The total length of pipe between flanges 1 and 2 is 75 cm. When the weight flow rate is 230 N/s, p1 = 165 kPa and p2 = 134 kPa. Neglecting pipe weight, determine the total force that the flanges must withstand for this flow. OO
