Challenge Problems
Push your limits with challenges.
Question 1
An open tank, 2 meters high, has a hole at 1 meter height where water flows out. If the water level drops to 1.5 meters, what is the velocity of the water exiting the hole? (Assume g = 9.81 m/s²)
💡 Hint: Remember to use the height difference to calculate the exit velocity.
Question 2
A circular pipe narrows from a diameter of 1 meter to 0.5 meters. If the fluid velocity before the narrowing is 3 m/s, calculate the velocity in the narrower section.
💡 Hint: Use the area and velocity relationship based on the conservation of mass.
