Question:

Water flows steadily through the piping junction, entering section 1 at 0.0013 m³/s. The average velocity at section 2 is 2.1 m/s. A portion of the flow is diverted through the shower head, which contains 100 holes of 1-mm diameter. Assuming uniform shower flow, estimate the exit velocity from the shower head jets.
