Supercritical flow is open channel flow with high flow velocity and depth less than critical depth. Subcritical flow has a low flow velocity and …
Continue ReadingBernoulli’s Equation is readily applied in fluid flow problems to understand the flow and to find the unknown parameters. It has pressure, …
Continue ReadingThe differential pressure flow meter, like the orifice, flow nozzle, and venturi meter, is used for pipe flow measurement. For each type, a …
Continue ReadingThe Manning equation is an empirical equation for uniform open channel flow. It can be used for water flow rate calculations in either man made or …
Continue ReadingNow we know how the energy of an ideal fluid flow is written in the form of an equation. And we know that this equation gives the total energy of …
Continue ReadingTwo of the most economically prosperous nations in the world own the lion’s share of watershed engineering. As this vital infrastructure ages, …
Continue ReadingOpen channel flow measurement is usually done with a weir or a flume. The weir or flume causes a change in water depth that correlates with water flow …
Continue ReadingIn the last two articles we discussed position, velocity, and acceleration of fluid particles in a flow. What causes fluid particles to move and …
Continue ReadingIn recent years new trends in hydrology have emerged because of high urban development. This necessitated reviews of theory and practice in this …
Continue ReadingIf velocity is a basic property of any fluid flow then the change in velocity, acceleration, is also an important attribute of fluid particles in a …
Continue ReadingLike any other mechanical system, the analysis of fluid flow or the mechanics of fluid flow has two parts: the kinematic analysis of fluid flow and …
Continue ReadingTo understand any problem or physical phenomenon, organize it into parts and consider each part separately and in association with other parts. …
