Challenge Problems
Push your limits with advanced challenges
A pipe has a varying diameter. If the velocity at the inlet is 3 m/s and the area is 0.2 m^2, determine the velocity at the outlet when the area is 0.1 m^2.
💡 Hint: Think about how the area changes and how that affects velocity.
A tank with a constant inflow of 5 L/min is experiencing an outflow rate of 2 L/min. What is the rate of change of liquid height if the tank area is 0.5 m^2?
💡 Hint: What does your mass balance tell you about the liquid level?
