Key Concepts
- -- Conservation of Momentum
- A fundamental principle stating that the momentum of a closed system remains constant in the absence of external forces.
- -- Reynolds Transport Theorem
- A mathematical formulation that connects the rate of change of a quantity within a control volume to the flow of that quantity across the boundary.
- -- Momentum Flux Correction Factor
- A factor that accounts for the variation in velocity profiles across a cross-section to accurately compute momentum flux.
- -- Control Volume
- A defined volume in space through which fluid may flow in and out, used for applying conservation laws.
- -- Hydraulic Conductivity
- A measure of a soil's ability to allow water to flow through its porous structure.
