###### Answer: p initial = p final

Conservation equations The Boltzmann equation can be used to derive the fluid dynamic conservation laws for mass charge momentum and energy. For a fluid consisting of only one kind of particle the number density n is given by {\displaystyle n=\int f\ d^ {3}p.}

Linear momentum translational momentum or simply momentum is the product of a body’s mass and its velocity: p = m v {\displaystyle \mathbf {p} =m\mathbf {v} } where p is the momentum m is the mass and v is the velocity. Momentum can be thought of as the “power” when a body is moving meaning how much force it can have on another body.

The law of conservation of momentum states that the total momentum of a closed system of objects (which has no interactions with external agents) is constant. Despite the fact that there is an energy loss momentum across a hydraulic jump is still conserved. This means that the flow depth on either side of the jump will have the same momentum …
