Challenge Problems
Push your limits with advanced challenges
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.
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.
