Water flows through the horizontal pipe shown in figure at a rate of 10 ft3/s. If viscous effects are negligible, determine the water speed at section (2), the pressure at section (3), and the flowrate at section (4).

(1) A = 1 ft Q = 10 ft/s P = 10 psi (2) A = 0.07 ft P2 = 5.0 psi (4) A3 = 0.2 ft V3 = 20 ft/s (3)
