1.9. Froude Number Similarity

Try these first

1. 1.

   Define the Froude number.

   Hint

   Think about the main forces at play in a flowing fluid.

2. 2.

   What is the purpose of dynamic similarity?

   Hint

   It relates to how accurately we can predict the behavior of systems.

3. 3.

   What is the Froude number primarily used for?

   • To measure temperature
   • To compare model and prototype
   • To determine fluid viscosity

   Hint

   It relates to fluid dynamics.

4. 4.

   True or False: Discharge is defined as the flow rate of a fluid.

   • True
   • False

   Hint

   Think of it as a speed measure for fluid.

5. 5.

   A small-scale model of a dam has a horizontal scale of 1/100. If the model can hold 500 m³ of water, what is the corresponding volume for the prototype?

   Hint

   Remember to cube the length ratio.

6. 6.

   If the Froude number for a model of a ship is 1.2 with a velocity of 4 m/s, what would be the corresponding velocity for a prototype with the same Froude number?

   Hint

   The Froude number is constant; focus on relationship between velocity and length ratios.
