Problem 3 (20 Points – Mass Conservation). At a piping junction, a water stream at 20°C is divided as shown in Figure P.3. Water enters the inlet at section (1) with a flow rate of 20 gal/min. In section (2), the average velocity is 2.5 m/s, and in section (3), a showerhead is attached to the outlet. There are 100 holes with an equal diameter of 1 mm at the showerhead opening. Assuming uniform shower flow and circular cross-section for all the pipes, estimate the exit velocity from each hole of the showerhead jets. Consider, 1 gal = 3.79 L. Figure P.3
