Challenge Problems
Push your limits with challenges.
Question 1
A jet of water strikes a vertical flat plate with a velocity of 15 m/s and a height of 2m. Calculate the total momentum exerted by the water on the plate per second.
💡 Hint: Set up the flow area and consider that momentum will be affected by both height and speed.
Question 2
How would the required force to hold a sluice gate change if the water height increases from 5m to 8m, while keeping velocity constant? Calculate the new force.
💡 Hint: Pressure increases with height; recalculate using hydrostatic pressure principles.
