Challenge Problems
Push your limits with challenges.
Question 1
A jet of water flows with a velocity of 10 m/s into a control volume of diameter 0.1 m. Calculate the momentum being transferred to the control volume when it exits.
💡 Hint: Remember the equation: Momentum = ρ * Q * V.
Question 2
In a horizontal pipe with varying diameters, the fluid's inlet diameter is 0.2 m and the outlet diameter is 0.1 m. If the inlet velocity is 5 m/s and density is 1000 kg/m³, what is the outlet velocity?
💡 Hint: Consider that the area changes as fluid flows from one diameter to another.
