A horizontal pipe, 10 cm in diameter, has a smooth reduction to a pipe 5 cm in diameter. If the pressure of
the water in the larger pipe is 8.00 104 Pa and the pressure in the smaller pipe is 6.00 104 Pa, what is the
flow speed of the water (in m/s) in the smaller pipe?
a. 0.0625 m/s
b. 6.53 m/s
c. 0.94 m/s
d. 42.67 m/s
e. 2 m/s
