Water pressurized to 3.5 x 10^5 Pa is flowing at 3.0 m/s in a horizontal pipe which contracts to 1/4 its former area. What are the pressure and velocity of the water after the contraction?
a. 2.3 x 10^5 Pa, 16 m/s
b. 4.2 x 10^5 Pa, 12 m/s
c. 5.6 x 10^5 Pa, 16 m/s
d. 3.0 x 10^5 Pa, 15 m/s
e. 2.8 x 10^5 Pa, 12 m/s
