Question 1.
What is a system in fluid mechanics?
Show hintHide hint
Think about the mass of fluid you are analyzing.
Question 2.
Define drag force.
Show hintHide hint
Relate this to the wind pushing against a moving car.
3Question 3.
What defines a control volume?
- A fixed amount of matter
- A space defined for fluid flow analysis
- An unbounded system
Show hintHide hint
Think about where the fluid flows.
4Question 4.
The drag force is responsible for which of the following?
- True
- False
Show hintHide hint
Consider whether drag helps or hinders movement.
Question 5.
A wind tunnel test shows a drag force of 5 N and a lift force of 8 N on a model. Calculate the resultant force acting on the model and discuss its implications for design.
Show hintHide hint
Use the Pythagorean theorem to find the resultant force.
Question 6.
Describe how you would set up an experimental study to understand lift forces on an airplane wing in a wind tunnel. Include considerations for scaling and measurements.
Show hintHide hint
Think about model dimensions and flow speeds relative to real aircraft.
