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.
