The demonstration of a hydraulic jump in rectangular open channel part- 2 !! Fluid mechanics -2 What is the hydraulic jump and its use? Industrial. The hydraulic jump is the most commonly used choice of design engineers for energy dissipation below spillways and outlets. A properly designed hydraulic jump can provide for 60-70% energy dissipation of the energy in the basin itself, limiting the damage to structures and the streambed. Types of Hydraulic Jumps – Undular Hydraulic Jump – Weak Jump – Oscillating Hydraulic Jump – Steady Hydraulic Jump – Strong Hydraulic Jump – What does Froude's number mean? The Froude number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross-section or between boulders. The denominator represents the speed of a small wave on the water surface relative to the speed of the water, called wave celerity. What is the length of a hydraulic jump? In civil engineering, the hydraulic jump is us
