Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for mass conservation in a control volume?
- Inflow = Outflow
- Mass = Volume x Density
- Total Force = Mass x Acceleration
💡 Hint: Remember this is the balance of mass.
Question 2
True or False: Incompressible flow indicates changes in density.
- True
- False
💡 Hint: Think about liquids, are they compressible?

Challenge Problems
Push your limits with challenges.
Question 1
A water jet strikes a stationary flat plate at a velocity of 15 m/s. Calculate the force on the plate if the area of the jet impact is 0.2 m².
💡 Hint: Calculate flow rate before substituting.
Question 2
Consider a control volume with a moving boundary at 5 m/s that encounters a water jet at 20 m/s. Find the thrust if the jet area is 0.5 m².
💡 Hint: Use inflow velocity reduction by the moving boundary.
