The hydraulic jump

The purpose of this experiment is to study the behaviour of a hydraulic jump and to quantify the hydraulic characteristics of stationary hydraulic jumps (e.g. downstream flow depth, rate of energy dissipation) over a range of discharges and Froude numbers. A hydraulic jump is a sudden transition from supercritical to subcritical flow, typically associated with large energy losses. Remember that the broad-crested weir induces the reverse flow transition, i.e. from an upstream subcritical flow to a downstream supercritical flow, with negligible energy losses.
