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.
