Key terms
- pressure
- Normal force exerted per unit area by a fluid. This chapter uses the concept when students calculate pressure, resultant force and equilibrium in static fluids.
- hydrostatic balance
- Pressure variation balancing fluid weight in a fluid at rest. It helps explain the reasoning required to calculate pressure, resultant force and equilibrium in static fluids.
- buoyancy
- Net upward pressure force equal to the weight of displaced fluid under the stated conditions. Its limit matters because gauge reference, geometry and density must be explicit.
- streamline
- Curve everywhere tangent to the instantaneous velocity field. This chapter uses the concept when students classify a flow and apply energy balance only after checking assumptions.
- Reynolds number
- Ratio comparing inertial and viscous effects in a flow. It helps explain the reasoning required to classify a flow and apply energy balance only after checking assumptions.
- Bernoulli equation
- Mechanical-energy relation along a streamline under its stated assumptions. Its limit matters because viscous loss, pumps, turbines and unsteadiness require an extended relation.
- control volume
- Defined region through whose boundary mass, momentum and energy may cross. This chapter uses the concept when students compute forces and reactions from control-volume balances.
- mass flow rate
- Mass crossing a section per unit time. It helps explain the reasoning required to compute forces and reactions from control-volume balances.
- momentum flux
- Transport of linear momentum through a control surface. Its limit matters because surface normals and velocity directions control the signs.
- material derivative
- Rate of change following a moving fluid particle. This chapter uses the concept when students reduce governing equations using geometry, symmetry and boundary conditions.
- continuity equation
- Local conservation equation for fluid mass. It helps explain the reasoning required to reduce governing equations using geometry, symmetry and boundary conditions.
- Navier–Stokes equation
- Momentum balance for a Newtonian fluid including pressure, viscous and body-force effects. Its limit matters because discarded terms must be justified rather than silently omitted.
- head loss
- Mechanical-energy loss per unit weight caused by friction and fittings. This chapter uses the concept when students select pipe-loss or external-flow relationships from geometry and regime.
- boundary layer
- Near-surface region where viscous velocity gradients are significant. It helps explain the reasoning required to select pipe-loss or external-flow relationships from geometry and regime.
