Hydraulic Jump Calculator
The hydraulic jump calculator analyzes the jump from a supercritical to a subcritical flow in a rectangular channel.
What Hydraulic Jump Calculator does
The Hydraulic Jump Calculator on Omni Calculator determines the parameters of a hydraulic jump in a rectangular open-channel flow, transitioning water from a supercritical to a subcritical state. Users input known values such as initial depth, velocity, or Froude number, and the tool computes the resulting sequent depth, wave speed, and energy loss. The output provides the physical measurements needed to analyze flow transitions in water conveyance systems. Omni Calculator's version presents a clean, single-purpose interface focused on fluid dynamics calculations. It requires only the essential input parameters—depth, velocity, or Froude number—to generate the sequent depth and energy dissipation results. The design emphasizes straightforward data entry and clear output of the calculated jump characteristics without unnecessary navigation or complex configuration options common in engineering software.

Best for
Civil engineers, environmental scientists, and students studying open-channel hydraulics who need quick, accurate calculations of jump height, wave speed, and energy dissipation in rectangular channels without complex software.
Limitations
- Designed specifically for rectangular channels, not natural or irregular channel shapes
- Input values must be in consistent units; the tool does not auto-convert between measurement systems
- Calculations assume ideal fluid conditions and may not account for real-world turbulence or sediment effects
Hydraulic Jump Calculator FAQ
- What physical quantities does the Hydraulic Jump Calculator compute?
- The calculator determines the sequent depth (post-jump depth), wave celerity, and energy dissipation rate for a hydraulic jump in a rectangular channel, given initial flow depth, velocity, or Froude number.
- Can the tool handle natural river channels or only rectangular geometries?
- No, the Hydraulic Jump Calculator on Omni Calculator is designed specifically for rectangular open channels; natural or irregular channel shapes require different hydraulic modeling approaches.
- Is prior knowledge of the Froude number required to use the calculator?
- No, users can input either the initial flow depth and velocity, or the Froude number directly; the tool computes the missing parameter automatically.
- What units should be used for input values in the Hydraulic Jump Calculator?
- Input values must use consistent units (e.g., meters and seconds, or feet and seconds); the calculator does not perform automatic unit conversions, so users must ensure dimensional consistency.
