A compressible fluid is flowing through a pipe with a constriction. The diameter of the narrow section is 1/2 the diameter of the wide section. The density of the fluid in the narrow section is 3/4 the density of the fluid in the wide section. If the velocity of the compressible fluid is 3.600 m/s in the narrow section, then what is the velocity of the fluid in the wide section?
A. 0.675 m/s
B. 0.805 m/s
C. 0.250 m/s
D. 0.333 m/s
E. 0.500 m/s
A. 0.675 m/s
