Challenge Problems
Push your limits with advanced challenges
A water jet of density 1000 kg/m³ exits a pipe at 5 m/s. Calculate the force exerted on the wall of the pipe if the exit area is 0.2 m².
💡 Hint: Think about how to calculate mass flow rate.
Two fluids at different velocities enter a junction: Fluid A at 3 m/s and Fluid B at 6 m/s. If the cross-sectional areas are known, find the resultant force acting at the junction due to the exiting flow.
💡 Hint: Compare areas and how they influence velocity.
