Challenge Problems
Push your limits with advanced challenges
A pipe has a diameter of 0.5m at the entrance and 0.2m at the exit. Water flows through the pipe at a speed of 5m/s at the entrance. Calculate the speed at the exit.
💡 Hint: Use the area of the circular cross-section to compute A.
1L of water flows into a tank with a 0.1 m² cross-section. If the height of the water rises 0.5 meters, what is the inlet velocity needed to achieve this rise in 2 seconds?
💡 Hint: Remember to convert cubic meters to liters when necessary.
