15.8 Steady Flow of a Fluid Stream

Up to this point we have restricted our study of impulse and momentum principles contained within a closed volume. In this section, however, we will apply the principle of impulse and momentum to the steady mass flow of fluid particles entering into and then out of a control volume. This volume is defined as a region in space where fluid particles can flow into or out of a region. The size and shape of the control volume is frequently made to coincide with the solid boundaries and openings of a pipe, turbine, or pump. Provide the flow of the fluid into the control volume is equal to the flow out, then the flow can be classified as steady flow.
