15. Conservation of Momentum
The chapter focuses on the principles of momentum conservation and the application of Reynolds transport theorem to derive conservation equations for mass and linear momentum in fluid mechanics. It includes practical examples and exercises to illustrate these concepts. The study emphasizes the use of control volumes in analyzing fluid systems and provides insights into the relationship between pressure forces and fluid motion.

What we have learnt
- The Reynolds transport theorem is fundamental for deriving conservation principles in fluid mechanics.
- The continuity equation represents the conservation of mass within a fluid system.
- Linear momentum conservation can be applied to practical scenarios such as fluid jet interactions with surfaces.
Key Concepts
- -- Reynolds Transport Theorem
- A fundamental theorem used to relate the change in mass and momentum in a control volume to the net flow of mass and momentum across its boundaries.
- -- Continuity Equation
- An equation stating that the mass influx and outflux in a control volume must be equal for steady fluid flow, often written as A1V1 = A2V2.
- -- Linear Momentum
- Momentum associated with fluid motion, defined as the product of mass and velocity; relevant in computing forces acting on a fluid due to changes in velocity.
