7.41 Flow through a horizontal 180 pipe bend is shown in Figure P7.12. The pipe diam- eter is constant at 15 cm, and the volume flowrate is 125 L/s. The pressure at the entrance port is 183 kPa, and the pressure at the exit port is 148 kPa. Determine the magnitude and di- rection of the force necessary to hold the elbow in place. Neglect the weight of the elbow and the fluid in the elbow in your calculations. 180 Horizontal elbow diameter = 15 cm Q = 125 L/s Water Pin = 183 kPa = 148 kPa Pout= Figure P7.12 rbend 25 cm
