Challenge Problems
Push your limits with challenges.
Question 1
A pipe tapers from 0.5 m to 0.25 m. If water flows at 1 m/s in the larger diameter, what is the velocity in the smaller diameter?
💡 Hint: Think about how areas compare.
Question 2
If water flows through a horizontal pipe, how would you calculate the force applied if the water exits at 10 L/min and impacts a wall, assuming it comes to a complete stop?
💡 Hint: Remember to relate mass flow and velocity to force.
