4. A 6-cm diameter horizontal water pipe expands gradually to a 9-cm diameter pipe. The walls of expansion section are angled 20 degree from the axis. The average velocity and pressure of water before the expansion section are 7m/s and 150 kPa, respectively. Determine the head loss in the expansion section and the pressure in the larger-diameter pipe.
