Water flows in a 0.15-m-diameter vertical pipe at a rate of 0.40 m³/s and a pressure of 550 kPa at an elevation of 25 m. Determine (a) velocity head at elevation of 20 m, (b) pressure head at elevation of 20 m, (c) velocity head at elevation of 55 m, (d) pressure head at elevation of 55 m. (a) Velocity head at elevations of 20 m: m (b) Pressure head at elevations of 20 m: m (c) Velocity head at elevations of 55 m: m (d) Pressure head at elevations of 55 m: m
