2 cards from this section. Quick, good the night before a test.
Define Froude Number.
Think about how gravity and inertia interact in fluids.
What is a distorted scale model?
Focus on the goal of fitting models within available space.
What ratio is maintained for dynamic similarity when modeling?
Think about fluid forces in use.
True or False: In distorted models, the vertical and horizontal scales must always be equal.
Consider the flexibility in model design.
In a specific case, a model's horizontal length is designed at a 1/300 scale and a vertical dimension at 1/60. If the prototype’s discharge is 180 m³/s, find the model’s expected discharge.
Start by calculating the scaling factors first.
A prototype depth measures 1.5m, and the scale for height in the model is 1/40. If the Reynolds number in the prototype is 15000, what would be the expected Reynolds number for the model?
Focus on what ratios are needed to maintain similarity.
