Open Channel Flow with no slope - Engineering Stack Exchange

In fluid mechanics and hydraulics, open-channel flow is a type of liquid flow within a conduit with a free surface, known as a channel. The other type of flow within a conduit is pipe flow. These two types of flow are similar in many ways but differ in one important respect: open-channel flow has a free surface, whereas pipe flow does not. WebFlow in open channels refers to any flow with a free surface. And in hydraulics, of course, we're mostly looking at, flow of water. There are different types of ... a quarter of the hydraulic diameter. S is the channel slope, and K is a factor which is different depending on what units we're working in.
