Water pressurized to 3.5 × 10⁵ Pa is flowing at 5.0 m/s in a horizontal pipe which contracts to 1/3 its former area. What are the pressure and velocity of the water after the contraction? A)2.5 × 10⁵ Pa, 15 m/s B)3.0 × 10⁵Pa, 10 m/s C)3.0 × 10⁵ Pa, 15 m/s D)4.5 × 10⁵ Pa, 1.5 m/s E)5.5 × 10⁵ Pa, 1.5 m/s
