Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows through a pipe with an area of 0.02 m² at a velocity of 10 m/s. If the area decreases to 0.01 m², what will be the new velocity?
💡 Hint: Apply the principle of conservation of mass.
Question 2
A force of 300 N is applied by a water jet on a perpendicular surface at a velocity of 15 m/s. Calculate the flow rate of the jet.
💡 Hint: Check units as you convert mass rate into volume flow rate.
