Momentum equation in open channel flow
WebIt is possible to formulate equations describing three conservation laws for quantities that are useful in open-channel flow: mass, momentum, and energy. The governing equations … WebThe momentum equation commonly used in most of the open channel flow problems is a linear-momentum equation. This equation states that the algebraic sum of all external …
