The energy slope refers to the gradient of the specific energy in an open-channel flow system, which represents the energy per unit weight of fluid as it moves through a channel. This slope is crucial for understanding the changes in flow characteristics and helps to analyze the energy losses due to friction and turbulence in the channel. The energy slope is typically represented as the difference in energy levels between two points along a channel, helping to visualize how energy is converted and dissipated in open-channel flows.
congrats on reading the definition of energy slope. now let's actually learn it.
