2 cards from this section. Quick, good the night before a test.
Define open channel flow.
Think about natural water bodies.
What is specific energy?
Relates to potential and kinetic energies.
What is the Froude number's significance in open channel flow?
Consider how gravity influences flow speed.
True or False: Hydraulic jumps always occur in subcritical flow.
Think about the flow direction.
A rectangular channel is 10m wide with a discharge of 20 m³/s. Calculate the flow depth and determine if the flow is subcritical or supercritical.
Use Q = A * v where A is the area of the flow.
Design a trapezoidal channel with a discharge of 30 m³/s at a certain slope. What dimensions would minimize energy loss?
Apply optimal design principles for trapezoidal cross-section.
