Fluid Mechanics 6.3 - Solved Example Problem 1 - Conservation of Mass and Momentum - Control Volume

In this segment, we apply the control volume principles of conservation of mass and momentum to obtain forces exerted by the flow on a common fluid component: a bend.

Module 6 - Conservation of Momentum:
The conservation of momentum can be derived from Newton's second law. The time rate of change of the linear momentum of the system = Sum of external forces acting on the system. After establishing a control volume, we can apply Reynold's Transport Theorem by substituting in momentum for B.

Student Learning Outcomes:
After completing this module, you should be able to:
1) Select an appropriate finite control volume to solve the conservation of momentum equation.
2) Apply conservation of momentum to the contents of a finite control volume to get essential answers
3) Explain how velocity changes in fluid flows are related to forces This material is based upon work supported by the National Science Foundation under Grant No. 2019664.
