3 cards from this section. Quick, good the night before a test.
Define open channel flow.
Think about environments like rivers and canals.
What is the role of gravity in open channel flow?
Consider how water flows downhill.
What distinguishes open channel flow from pipe flow?
Consider the surface of the liquid.
True or False: The pressure at the free surface in open channel flow is atmospheric.
Recall what 'free surface' means.
A rectangular channel has a width of 2 m and a depth of 1 m. Calculate the hydraulic radius.
Divide the area of flow by the total wetted perimeter.
A canal has a flow depth of 1.5 m and velocity of 4 m/s. Calculate the Froude number and determine the type of flow.
Use the gravitational constant g = 9.81 m/s² for calculations.
