Flashcards: Hydraulic Flow Dynamics and Design — 10 cards

Hydraulic jump — energy dissipation?

Converts supercritical to subcritical flow, reducing energy.

Hydraulic jump — definition?

Transition from supercritical to subcritical flow.

Open channel surface profile — type?

Shape depends on flow regime and slope, e.g., horizontal or inclined.

Supercritical flow — Fr?

Froude number greater than 1.

Flow criticality — condition?

Occurs at Froude number (Fr) = 1, transition point.

Subcritical flow — Fr?

Froude number less than 1.

Froude number — formula?

V / √(gD).

Energy dissipation — during jump?

Energy converted to turbulence and heat.

Energy loss (ΔE) formula?

(V₁² - V₂²) / 2g.

Hydraulic jump — purpose?

Dissipate energy, prevent erosion.
