C. Uniform Flow (Manning’s Equation) 1. Manning’s Equation: The normal depth is used to design artificial channels in a steady, uniform flow and is computed from Manning’s equation: =𝐴𝑉= 1.486 𝑛 (𝐴 2⁄3)( 1 ⁄2) Equation 2F-2.01 where:

Web21. feb 2024. · Assuming free-fall, calculate the critical depth of the flow. This is the same as a weir equation, setting the height of the weir above the invert of the channel as zero. The normal equations for flow in an open channel fall apart when the depth is critical. To overcome this, go say 3 depths back upstream and add 10% to the depth. WebIn fluid mechanics and hydraulics, open-channel flow is a type of liquid flow within a conduit with a free surface, known as a channel. [1] [2] 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.
