Document Summary
Objectives: use control volume analysis to determine forces associated with fluid flow. Reynolds transport theorem (by setting b = ___ and b = __) d. n)da represents the mass flow rate through area element da into or out of the cv. For a fixed control volume (no motion or deformation of control volume), vr = _ and the linear momentum equation becomes. Note that the momentum equation is ______ equation, and thus each term should be treated as a vector. Most momentum problems considered in this text are steady. Where the subscripts o and i refer to the outlet and inlet ports, Notice that the product of corresponds to the mass per unit time times velocity, or momentum per unit time, which has the same units as force. As long as v is uniform at the control surface, eq. (2) applies to any m control volume, including one that is moving, deforming, or both.
