A 6-cm-diameter horizontal water pipe expands gradually to a 9-cm-diameter pipe.. The walls of the expansion section are angled 108 from the axis. The average velocity and pressure of water before the expansion section are 7 m/s and 150 kPa, respectively. Determine the head loss in the expansion section and the pressure in the larger-diameter pipe. Water 7 m/s 150 kPa 6 cm 9 cm
