Question: Water at 20°C flows through the piping junction in the figure, entering section 1 at 20 gal/min, the average velocity at section 2 is 2.5

Water at 20°C flows through the piping junction in the figure, entering section 1 at 20 gal/min, the average velocity at section 2 is 2.5 m/s. A portion of the flow is diverted through the showerhead, which contains 100 holes of 1-mm diameter. Assuming uniform shower flow, estimate the exit velocity from the showerhead jets.
