Water pressurized to 3 × 10⁵ Pa is flowing at 5.0 m/s in a pipe which contracts to 1/2 of its former area.What are the pressure and speed of the water after the contraction? (Density of water = 1 × 10³ kg/m³. ) A) 2.6 × 10⁵ Pa,10 m/s B) 3 × 10⁵ Pa,2.5 m/s C) 3 × 10⁵ Pa,10 m/s D) 4.6 × 10⁵ Pa,10 m/s E) 2.6 × 10⁵ Pa,2.5 m/s
