2 cards from this section. Quick, good the night before a test.
What is the Froude number used for in hydraulic engineering?
Think about how gravity plays a role in flow dynamics.
Define Reynolds number.
Consider where flow patterns might change.
What is the definition of the Froude number?
Focus on the role of gravity in fluid behavior.
True or False: Distorted models maintain the same scale in all dimensions.
Consider how engineers resolve physical space constraints.
A hydraulic model designed with a horizontal scale of 1/250 and a vertical scale of 1/50 needs to maintain Froude number similarity. If the prototype's speed is 10 m/s, what should the model's speed be?
Remember to apply the square root to the horizontal scale ratio.
If a prototype flow has a measured depth of 3 m and utilizes a specific viscosity, how do you ascertain the corresponding depth in a distorted model with a height scale of 1/30?
Directly multiply the prototype depth by the height scale.
