A fluid flows in steady flow through a pipe. The pipe has a circular cross section, but its radius varies along its length. The mass of the fluid passing per second at the entrance point (radius R) of the pipe is Q1 while that at the exit point (radius R/2) is Q2. Then, Q2 is equal to
A. \(\frac{1}{4}\) Q1
B. Q1
C. 2Q1
D. 4Q1.
