Challenge Problems
Push your limits with challenges.
Question 1
A tank releases water at 5 m/s through a pipe that narrows down. If the diameter of the pipe decreases by half, calculate the new velocity of water and the force exerted at the pipe's exit if the exit area is 0.05 m².
💡 Hint: Remember to use the continuity principle that A₁V₁ = A₂V₂.
Question 2
Determine the effect of external forces on momentum conservation in a scenario where water exits a tank into open air. How would you analyze the forces acting on the jet?
💡 Hint: Draw a control volume diagram to visualize forces at play.
