$$\text { If the control volume equation for a flow is } \eta _ { 2 } \rho _ { 2 } A _ { 2 } V _ { 2 } = \eta _ { 1 } \rho _ { 1 } A _ { 1 } V _ { 1 } \text {, the flow may be: }$$
A) Uniform flow into and from a fixed volume
B) Steady, uniform flow in a pipe
C) Uniform flow in a conduit
D) Steady, one-dimensional flow in a channel

Steady, uniform flow in a pipe
$\text {The flow must be steady, so that leaves either B or D
. It must also be uniform so }$$\text {the variables can be removed from inside the integral of Eq. 4.3.12.}$
