2 cards from this section. Quick, good the night before a test.
Define Froude number.
Think about its relationship to gravity.
What is the formula for velocity ratio?
Recall the relationship between velocity and length ratios.
What is the main purpose of the Froude model law?
Think about how gravity plays a role in fluid dynamics.
True or False: Discharge ratios are solely based on velocity.
Consider how area influences discharge.
You have a prototype with a discharge of 200 m³/s, scale lengths of 1/100 for width and 1/50 for height. Calculate the model's discharge.
Break the scaling down and apply the ratios step by step.
Given a prototype force of 300 N and a model scale of L_r = 1/300, what is the resistance in the model?
Remember to cube the length ratio for force calculations.
