All you need to know about your Hydraulic Jump lab experiment report

Updated: Jun 27



A hydraulic jump 🌊 is a phenomenon that is frequently observed in open channels such as rivers, canals, spillways and weirs and is engineered for purposes of dissipating excess amounts of energy.


A hydraulic jump is formed when high-velocity liquid flow is discharged into a zone of lower velocity, creating an abrupt increase in depth hence, dissipating huge amounts of energy ⚡️.


This energy is the alteration of the flow’s initial kinetic energy to potential energy with some energy lost unavoidably in the form of friction, turbulence, eddying, heat and noise in the process.


The distinctive behaviour of supercritical flow and sub-critical flow is analysed to the extent of understanding the reason for the formation of the hydraulic jump.



Moreover, the parameter of the Froude number (Fr) is very useful towards the understanding of the occurrence of energy dissipation and the creation of the hydraulic jump. Conservation equations such as mass, linear momentum, Froude number and energy are used to investigate and detail analyse the flow of open-channel.
