Challenge Problems
Push your limits with advanced challenges
A water jet at a velocity of 20 m/s enters a nozzle with a cross-sectional area reduction, resulting in a pressure change of 2000 Pa. Calculate the change in momentum for the water.
💡 Hint: Know the relationship between pressure, area, and velocity variation.
In a turbulent flow through a pipe, the velocity increases from 3 m/s to 6 m/s at a bend. Calculate the net force acting on the fluid.
💡 Hint: Focus on how momentum is influenced by velocity changes at the bend.
