Water pressurized to 4 * 10⁵ Pa is flowing at 5.0 m/s in a pipe which contracts to 1/3 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 * 10⁵ Pa, 15 m/s B) 3 * 10⁵Pa, 10 m/s C) 3 *10⁵ Pa, 15 m/s D) 4 * 10⁵Pa, 1.5 m/s

Using the principle of conservation of mass and Bernoulli's equation, the speed increases to 15 m/s and the pressure decreases to 3 x 10^5 Pa after the contraction.
