Water from a large tank discharges into the atmosphere through the pipeline shown in the figure.Calculate (a) the discharge velocity V at the exit of the pipeline (station 2): (b)

the head loss hy; and (c) the volume flow rate Q. Assume constant diameter of the pipeline, d = 15 cm, and roughness e/d= 0.0017. Use Moody's formula (Eq. 6.48 in the textbook).
