Water flows through the horizontal branching pipe shown in the figure below at a rate of \( 8 \mathrm{ft}^{3} / \mathrm{s} \). If viscous effects are negligible, determine (a) the water speed at section (2), (b) the pressure at section (3), and (c) the flowrate at section (4). Assume \( Q_{1}=8 \mathrm{ft}^{3} / \mathrm{s}, A_{1}=1 \mathrm{ft}^{2}, p_{1}=10 \mathrm{psi}, A_{2}=0.07 \mathrm{ft}^{2}, p_{2}=6.3 \mathrm{psi}, A_{3}=0.2 \mathrm{ft}^{2}, V_{3}=25 \mathrm{ft} / \mathrm{s} \). First choose an equation to model the flow. Calculate the water speed in \( \mathrm{ft} / \mathrm{s} \) at point (cross-section) (2). \( v_{2}= \) \( \mathrm{ft} / \mathrm{s} \) eTextbook and Media Part 3 Calculate the pressure at (3) in psi. Calculate the flow rate at (4) in \( \mathrm{ft}^{3} / \mathrm{s} \). \[ Q_{4}= \] eTextbook and Media
