A 6-cm-diameter horizontal water pipe expands gradually to a 9-cm- diameter pipe. The walls of the expansion section are angled 30° from the horizontal. The average velocity and pressure of water before the expansion section are 7 m/s and 150 Ka, respectively. Determine the pressure (KPa) in the larger-diameter pipe. 6 cm 9 cm Water 7 m/s 150 kPa
