Open Channel Flow

Across
  1. 2. Fr < 1; velocity is low enough that small disturbances propagate upstream and downstream
  2. 5. Velocity of liquid does not change from one section to another. The cross-section and depth must be constant
  3. 6. Velocity at a particular point in the channel varies with time
  4. 7. Velocity at a particular point in the channel does not vary with time
Down
  1. 1. Fr > 1; velocity is high enough that small distubances can only propagate downstream
  2. 2. High Re, above threshold
  3. 3. Low Re, below threshold
  4. 4. Velocity, depth and cross-section vary continuously
