Show hintHide hint
Think about how gravity affects fluid flow.
Question 2.
What does Reynolds Number help predict?
Show hintHide hint
Consider how viscosity affects flow.
3Question 3.
What is the primary use of the Froude number?
- To determine viscosity
- To compare inertial forces to gravity
- To calculate flow discharge
Show hintHide hint
Think about how gravity impacts fluid dynamics.
4Question 4.
Is the Reynolds number related to viscous forces? (True/False)
- True
- False
Show hintHide hint
Consider how viscosity affects fluid movement.
Question 5.
A champion swimmer competes in a pool that is modeled at a 1/2 scaling of length. If their actual swimming time is 50 seconds for a length of 100 meters, calculate the modeled time for the swimming in a modeled pool if the Froude number is maintained.
Show hintHide hint
Remember to calculate the velocity ratio properly.
Question 6.
In river modeling, if a prototype discharge is 300 m³/s and the scaling ratio is 1:100, calculate the discharge needed for the model keeping in mind the discharge ratio's influence.
Show hintHide hint
Focus on using discharge ratio in relation to the given scaling.
