1.4. Discharge Ratio

Try these first

1. 1.

   What is the formula for discharge ratio?

   Hint

   Think about the relationship between volume and time.

2. 2.

   Define Froude Number in your own words.

   Hint

   Consider how it relates to flow conditions.

3. 3.

   What must be equal in both the model and prototype for Froude similarity?

   • Velocity Ratio
   • Froude Number
   • Area Ratio

   Hint

   This number relates inertial to gravitational forces.

4. 4.

   True or False: Discharge is the product of area and velocity.

   • True
   • False

   Hint

   Think about how flow is quantified through an area.

5. 5.

   A prototype has a discharge of 300 m³/s with a horizontal scale ratio of 1:100 and a vertical ratio of 1:50. Calculate the model discharge.

   Hint

   Focus on how each scale affects the discharge calculation.

6. 6.

   If the Froude number for the prototype is 0.8, what does this imply about the model's design requirements?

   Hint

   Think about how maintaining ratios affects fluid similarity.
