Water at 20°C flows steadily through the piping junction in Fig. P3.32, entering section 1 at 20 gal/min. The average velocity at section 2 is 2.5 m/s (d=1.5 cm). A portion of the flow is diverted through the showerhead, which contains 100 holes of 1-mm diameter (d=4 cm inlet, d=2 cm). Assuming uniform shower flow, estimate the exit velocity from the showerhead jets.
